You’re right, they should have just starved instead! So enlightened, thanks for setting us all straight!

The only people who don’t need credit to live are rich enough that money will never be out of their reach.

Also, your credit cards are a different kind of “loan” - revolving - vs those other debts, which are installment. Having a mix of the two will improve your credit. They literally want it to be impossible to have good credit without the cards.

The first time I wanted to finance a car I discovered I have what’s called a “thin file.” My (interest free) student loan wasn’t reporting to all 3 agencies. I was able to get my dad to co-sign. I was 26. Discovered then that being told “never ever ever own a credit card” (by my dad!) was very bad advice. Get one with a low limit and use it to pay the same bill every month. Credit! Now other places trust that you pay your bills.

I’ve since gotten several cards (it’s been nearly a decade) and they each serve a different specific purpose. I purposely target high signing bonuses and my purchases are better protected. My limits are stupid high, which I guess is nice but I’ll never put that much on so it’s a bit pointless. Then again, knowing I have access to that if things ever become dire is nice.
