Welcome back to

(00:00):
The Wealth Effect.
I'm your host,
Green Moon.
Today, we're talking
about credit cards.
Credit cards
are everywhere.
Are they a financial
tool or a financial trap?
We'll explore the dual nature of credit
cards, revealing how they can either build
or destroy wealth, depending
on how they are used.
The goal is not to vilify credit,

(00:21):
but to understand it, as it gives you
access, leverage,
and options.
But it also tempts you into shortcuts,
comfort, and debt that
compounds while you sleep.
Let's fill
your pocket.
A brief history
of credit cards.
The birth of the modern
credit cards started in 1950.

(00:42):
It started
over dinner.
In 1950, a businessman named Frank
McNorman had dinner at a New York City
restaurant and realized he
had forgotten his wallet.
Embarrassed, he vowed to create a system
so people wouldn't have
to carry around cash.
That moment sparked the creation
of the dinner club card.

(01:03):
The first multi-purpose
charge card.
Initially accepted at 27 restaurants, it
allowed members to pay with a card and
settled their balance
at the end of the month.
It wasn't a credit card as we know it
today, but it was like a prototype.
And a new idea was
born out of that.
A cashless system.

(01:24):
Then, in the 1960s, they introduced
magnetic strips, banking partnerships,
and more consumer-facing
innovation.
Major players entering the field were Bank
of America, which launched Bank AmeriCard,
later known
as Visa.
Master Charge, now known as
MasterCard, followed soon after.

(01:46):
Other banks and retailers created private
label cards to tap into this trend.
As more merchants began to accept these
cards, the idea of buy now, pay later,
moved from
novelty to norm.
And with that convenience
came something else.
Debt.
By the 1980s, credit cards were no
longer exclusive to the well-traveled

(02:08):
businessmen.
Thanks to aggressive marketing,
changing consumer behavior, and growing
appetite for convenience, credit
cards became an American staple.
People were now using them, not just for
travel or emergencies, but for groceries,
gas, electronics,
and even clothes.
It was the era of
spending as a lifestyle.

(02:29):
And with that, credit cards transformed
from a financial tool
into a cultural symbol.
Some credit cards even became status
symbols, like the American Express
Platinum or the exclusive
Centurion Black Card.
Fast forwarding to today, over 1.1 million
credit cards are currently in circulation

(02:50):
in the U.S.
alone.
We live in a world where you can tap
your phone to buy coffee, auto-pay
subscriptions without thinking, and
even apply for new credit cards from
your couch.
Credit cards now
serve multiple roles.
Financial lifelines for emergencies,
reward engines for travel, cash back,
and perks, credit score builders or

(03:12):
destroyers, depending on the usage.
Debt traps, unfortunately for millions,
who don't understand the cost of interest.
We've moved from physical swipes to
digital wallets, from paper statements to
real-time push
notifications.
But the one thing
that hasn't changed?
The psychology.
As Ryan Holiday might say, technology

(03:33):
changes, human nature doesn't.
The temptation to
overspend is the same.
The emotional pull of buy
now, deal later, remains.
What's evolved is the ease of
indulgence and the illusion of control.
They've become a status
symbol, convenience tool.

(03:54):
Let's get into how
credit cards work.
Credit cards
aren't good or bad.
They're
just a tool.
They can build wealth, streamline
budgets, and generate rewards.
Or, they can erode financial
stability, if misused.
Understanding where they come from and how
far they've come can help you decide how
to use them
going forward.

(04:15):
At their core, credit cards
are revolving credit lines.
This means the issuer, usually a bank
or financial institution,
offers you a certain
credit limit.
And you are free to
borrow against it.
Repay it and
borrow again.
Think of it as
a reusable loan.
You can access it anytime, as
long as you're under your limit.

(04:37):
Let's say your credit
limit is $5,000.
You spend $1,000.
Now you have
$4,000 available.
Repay back
the $1,000.
Now your credit line
is back up to $5,000.
Simple, right?
But here's where it gets
tricky and expensive.
Each month, you receive a
statement showing how much you owe.

(04:58):
You're given
two options.
The first one,
paying in full.
This allows you
to avoid interest.
But the second, pay
the minimum due.
You incur interest on
the remaining balance.
Most Americans don't realize that only
paying the minimum is like signing a
contract with compound interest

(05:18):
that works against you.
You're not just
postponing your payment.
You're feeding
a debt snowball.
This is because credit cards
typically have a high interest rate.
As of 2024, the average APR annual
percentage rate on a credit card in the US
is around 24%.
Let that sink in.

(05:39):
That's significantly higher than personal
loans, which are typically 7% to 12%.
Auto loans
from 4% to 7%.
And even private student
loans, which are 8% to 12%.
If you carry a $5,000 balance and only
make the minimum payment, at that rate,
you pay thousands of dollars

(05:59):
in interest over time.
And it will take years to
pay off if it ever does.
This is how banks
make their money.
Not just from few who pay their balance
in full, but from those who don't.
As Jim Rohn said, what is easy
to do is also easy not to do.
It's easy to pay off your balance monthly,

(06:21):
but it's also easier to push it off until
that small decision
becomes a financial drain.
Let's give
another example.
Let's say you owe $3,000 on
a credit card with 24% APR.
Your monthly payment each month is about
2% of the balance, or $60 in this case.

(06:41):
It could take over 15
years to pay that off.
And you would pay more than
$4,000 in interest alone.
That's not
purchasing power.
That's future income, mortgaged
for a short-term sacrifice.
This is a system that rewards the
disciplined and punishes the impulsive.

(07:03):
Credit cards aren't
inherently bad.
They can build your credit, provide fraud
protection, and even reward
you like cash back or
travel points.
They are designed for banks to
profit, not your financial health.
Credit cards present
you with a challenge.
Can you master them, or
will they master you?
It all depends on how you

(07:24):
handle that moment at checkout.
That tiny decision to
swipe and delay payment.
And this is how credit cards
play into the human psychology.
Their instant
gratification.
The idea of buy
now and pay later.
The present bias, where we value today's
pleasure more than tomorrow's pain.

(07:46):
Social comparison.
As more and more people try to keep up
with social media images, they tend to
spend it all
on credit.
That's why credit cards
feel much easier than cash.
And it's not
just speculation.
It's been studied.
Behavioral economists have long understood
that people spend more when using credit
cards than when
using cash.

(08:06):
One MIT study showed that people were
willing to pay up to 100% more for the
same item when using credit
cards versus physical cash.
Why?
Because credit cards disconnect
the purchase from the pain.
When you hand over cash,
there's a visible exchange.
You feel it.

(08:27):
When you swipe plastic or tap
your phone, it's abstract.
Almost fictional.
There doesn't seem to
be a tangible loss.
No moment of
sacrifice.
And that creates the
illusion of abundance.
If you're paying cash,
there's a brief pause.
You open
your wallet.
You count
the bills.
You feel the weight of

(08:47):
what you're giving up.
But with credit cards, it's
a tap, swipe, and done.
The dopamine
hit stays.
The costs get pushed
into the future.
And that's
the illusion.
Credit cards make it easy to
feel rich while becoming poor.
We now live in a world that
rewards instant gratification.

(09:08):
Buy now.
Pay later.
0% down.
12 months
interest free.
That sounds
like freedom.
But what it really is,
is debt in disguise.
It's easy to swipe today and
ignore the statement tomorrow.
Until the
interest kicks in.
Until the
balance grows.
Until the illusion collapses

(09:29):
under the weight of reality.
And here's the
real cost of free.
What they don't tell you on the flashy
rewards websites or point
hacker YouTube channels.
That free vacation you're chasing with
points might cost you 24% in APR if you're
carrying a balance.
That's a $1,000 TV you couldn't afford

(09:50):
in cash becomes $1,400 after a year of
minimum payments.
Credit cards don't
give you free money.
They give you expensive
money as the hidden tax.
It's not wealth.
It's leverage.
And leverage
cuts both ways.
And it's about training your
mind, not just your wallet.
As Brian Holliday would put it, What

(10:10):
blinds us is not the tool itself,
but how we
choose to use it.
Credit cards
aren't evil.
They are neutral.
But in the hands of undisciplined
people, they amplify bad habits.
Such as impulses
becomes overspending.
Convenience becomes
complacency.
Just this once
becomes a lifestyle.

(10:31):
The solution
isn't fear.
It's awareness.
Learn to pause
before you swipe.
Ask yourself, Would I make the same
decision if I had paid in cash?
Is this what I need
or what I want?
Will this still feel like a good
idea when the statement arrives?
That pause, that single moment of clarity,

(10:52):
is what separates the
wealthy from the in-depth.
But it's easy to fall into emotional
spending when marketing taps into the fear
of missing out,
prestige, or rewards.
The way out.
There's no magic bullet, but there is a
mindset shift in order to
avoid credit card debt.
Always aim to pay more

(11:13):
than the minimum payment.
As much as you
can afford.
Build a debt payoff plan, targeting
high-interest credit cards first.
Or, better yet, don't
carry a balance at all.
You can't outsmart banks, but you can
choose to fight them or feed them.
As banks and many credit cards
companies tend to prey on habits and

(11:36):
vulnerabilities.
And they
don't hide it.
They pre-approve
people.
They offer 0%
intro rates.
Big limits for people
with small incomes.
And it's not illegal,
but it is predatory.
They don't
encourage spending.
They engineer it.
This feeds into
the present bias.

(11:57):
Where today feels real, and
tomorrow feels imaginary.
The present bias is a well-documented
psychological tendency.
We prioritize immediate pleasure
over long-term well-being.
It's why we procrastinate
on paying off debt.
It's why we swipe a card, even
though we know we can't afford it.

(12:19):
Unfortunately, when it comes to credit
card spending, it's the inverse.
We enjoy in imagination and suffer
in reality when the bill comes.
And one of the most powerful
traps is social comparison.
You see friends posting about vacation,
scrolling past $2,000 outfits online.

(12:41):
You watch YouTube videos with luxury
hauls, new cars, high-rise apartments,
and something whispers to
you, you deserve that too.
But here's what few
would say out loud.
Many people are financing
their lifestyle with debt.
The highlight rules you're comparing
yourself to are often borrowed,

(13:03):
leased, or paid
in payments.
They're trying to keep up with
people who aren't even ahead.
Chasing prestige with credit is
like digging a hole to look taller.
All that being said, there are
powerful uses for credit card.
When credit cards are used wisely,
they can be a tool to build credit,

(13:24):
provide emergency liquidity, fraud
protection, and build up points,
miles, and cash back.
The key is not the
card, it's the behavior.
But there's a golden rule
when it comes to credit cards.
If you can't pay off it, if you can't pay
it off in full, you shouldn't be using it.
Paying in full every month, avoiding

(13:45):
interest, and using only what you can
afford turns the trap
into a powerful tool.
When it comes to building your credit
with credit cards, it's your financial
reputation.
It's like your
report card.
It determines whether you qualify for a
mortgage, the interest rate on any loan,

(14:06):
whether the landlord will let you
lease the apartment, and even insurance
premiums, or employment
in some industries.
A good credit score isn't
just about borrowing.
It's about trust.
Using credit cards responsibly,
keeping low balances, paying on time,
building a history
of reliability.
Let's talk about a few

(14:26):
benefits of credit cards.
Emergency liquidity.
Life is
unpredictable.
Medical bills can arise
from accidental injuries.
Your car
breaks down.
A flight gets canceled, and
you're stuck in another city.
When used wisely, a credit card
can serve as a financial parachute.

(14:47):
A bridge between
calm and crisis.
But here's the key.
It's a backup plan.
Having access to credit isn't
the same as depending on it.
But when used sparingly, it offers
peace of mind in turbulent times.
Fraud protection.
One of the underrated advantages
of credit cards is protection.

(15:08):
If your debit card is hacked, there's
actual cash gone, frozen, unavailable.
With credit cards, dispute fraudulent
charges, you're protected under federal
laws like Fair
Credit Billing Act.
You're not liable for any
unauthorized transactions.
It's like having a
financial body...
It's like having a financial

(15:30):
bodyguard every time you swipe.
And lastly,
rewards.
Let's be honest.
Who doesn't like free
travel, cash back, or perks?
Credit card rewards can be valuable if
you're not paying interest to earn them.
Because what's the point of earning
1.5% cash back if you're
paying 24% in interest?

(15:51):
You're not winning.
That's paying $1.50
to get 15 cents back.
But if you're paying your balance in full
every month, rewards are
just the icing on top.
They're what you earn for being
smart, consistent, and disciplined.
The behavior is
key, not the card.
Here's the
core message.

(16:12):
Having a credit card doesn't
cause you to go into debt.
Choices do.
When you use credit as a
substitution for income, you suffer.
When you use a tool for
discipline, you win.
The difference between drowning in
interest and flying on
points is not the plastic.

(16:32):
It's the person
holding it.
Responsible credit usage means
you pay in full every month.
You never spend more
than you can afford.
You track and
review every charge.
You treat your credit like a
tool and not an extra income.
This isn't about
being perfect.
It's about being

(16:52):
intentional.
Credit scores.
Credit cards directly impact FICO
scores, which affect your mortgage rates,
auto loans, and even job
opportunities in some industries.
A three-digit number that determines
your access to money, opportunities,
and even some
employment.
And one of the biggest items in shaping

(17:13):
that number is your credit card.
The most widely used credit score in
America is the FICO score, which is a
range from
300 to 850.
It's based on five core categories,
the first being payment history,
which counts for
35% of your score.
This one's a big one.
And the golden rule

(17:35):
is always pay on time.
One missed payment can drop your score by
50 to 100 points and stay on your report
up to seven years.
Your credit card bill
isn't just a payment.
It's a promise you either
keep or break every month.
The second one being credit card
utilization, which accounts for 30% of

(17:57):
your score.
This measures how much of your
available credit you're using.
If you have a $10,000 credit card limit
and your balance is $3,000, you're using
30% of your
balance.
Experts say to keep it
under 30%, ideally under 10.
High balances, even if paid in
full, signal a risk to lenders.

(18:19):
The third one, length of credit history,
which accounts for 15% of your score.
This is about time.
The longer you have an
account open, the better.
It's why people tell you that first
credit card you opened up in college,
don't close it.
It's an anchor to
your credit age.
It shows the lender that
you're not new to credit cards.

(18:41):
And the other influences are new credit,
which accounts for 10%
of your credit score.
Opening too many credit cards in a short
period of time lowers your score because
it looks like
desperation.
There's also credit mix, which
accounts for another 10%.
Having both revolving credit and
installment loans, such as auto loans,

(19:02):
student loans, mortgages, show many
financial institutions that you know how
to manage different
financial tools.
So yes, credit cards influences four out
of the five categories in your score.
Think of credit
cards like a mirror.
It reflects your habits, your
consistency, your values.
If you use them with intention, your

(19:23):
credit score becomes a symbol of your
financial health.
If you use them impulsively, your
score becomes a warning sign.
In modern finance, your credit behavior
is your character measured mathematically.
Are rewards
worth it?
Well, it depends
on the user.
If you're carrying a balance, rewards

(19:43):
are like offering a lottipop to someone
bleeding out.
They distract from the real issue
and cost more than what they give.
If you're financially disciplined,
rewards are a rebate, a perk, a calculated
bonus, not a reason
to overspend.
But in the end, the
smartest reward is freedom.

(20:06):
Freedom from debt, freedom from marketing
games, freedom to choose based on values,
not points.
And that's worth more than
any cashback could ever be.
Now let's talk about a few
common myths about credit cards.
What you don't
know can cost you.
In the age of infinite

(20:26):
information, ignorance is a choice.
And when it comes to credit cards,
misinformation isn't just harmless,
it's expensive.
There's no shortage of financial
advice floating around.
Some passed down from old family members,
others picked up from TikTok or friends
who mean well, but

(20:47):
don't know any better.
As Ryan Holliday would say, just because
it's common doesn't mean it's wise.
Myth number one, you have to
carry a balance to build credit.
This is one of the most dangerous
and costly myths of them all.
It sounds logical.
If I have a balance, it shows
I'm using my credit card.
That builds my

(21:08):
credit score, right?
That's not true.
Your credit score improves when you use
your credit card and pay it off on time.
Carrying a balance does nothing
to help your credit score.
And in fact, it
could make it worse.
Myth number two, closing old credit
cards helps your credit score.
That's actually the

(21:28):
complete opposite.
You might think
not using it.
Credit card scoring doesn't
reward you for closing your cards.
In fact, it
punishes you.
And here's why.
Your credit utilization ratio goes
up because you closed a credit card,
because you reduced your
total available credit.
The average age of your credit card goes

(21:48):
down especially when
closing a very old account.
Both negatively impact
your credit score.
The better move would be to cut it up or
use it occasionally on small purchases,
but never close it.
Myth number three, one
late payment won't hurt me.
This is also a very dangerous myth

(22:09):
because it's rooted in complacency.
it's just one
more bill.
I'll pay it
next week.
It's no big deal.
Actually, it's
a very big deal.
A single late payment can drop your credit
score from 50 to 100 points depending on
your credit profile, stays on your account
for seven years, and it can increase the

(22:31):
interest rate on
your other accounts.
Myth number four, maxing out your credit
card is fine as long as you pay it off at
the end of the month.
Another myth that sounds reasonable,
but harms your credit
score, even if you pay your
full balance.
Maxing out your credit cards before the
statement date can spike your credit
utilization, making it look like

(22:51):
you've overextended yourself.
Credit bureaus don't
see your daily activity.
They see your report balance at the
time of the statement, like a snapshot.
So as a final summary, here are some
best practices for credit cards.
pay them in full every month, never spend
more than you can pay back, set up auto
payments to never miss a payment,

(23:13):
only use 10-30% of your total credit
limit, check statements frequently for
errors or fraud, and avoid cash advances
as they carry even
higher interest rates.
Credit cards aren't evil,
they are indifferent.
It all depends on who
wields it and how.
used with awareness, strategy, and

(23:33):
discipline, credit cards can enhance
your financial
life.
The enemy is believing that tomorrow's
you will clean up today's mess.
You don't have to
cancel every card.
Don't aim to
beat the system.
Aim to become the kind of
person who doesn't need to.
Thank you for
listening.
Until next time.
