Just because you have a lot of money doesn't mean you'll make payments on a loan.
The fact that so many things require a high credit score is a forcing function for you to take on these debt instruments, and the credit score is a way for the system to optimize that it get its money.
The entire system is gamed against the consumers unwittingly or unwillingly forced to participate.
Not a bad way to buy stuff if you have the means to pay it off.
Does it really?
I have a very high credit score but putting a large charge on one credit card (nowhere close to maxing it out though) dramatically drops my credit score for one month until I pay it off in full at the end of the month.
I pay my child's tuition in full for the year each August (school in California is way too expensive so it's a lot of money, but that's a different topic). I put it on the credit card to get some cash back. My credit score drops by about 150 points right away. Once I get the bill at the end of the cycle and pay it off, the credit score goes right back to where it was before. I don't get any bump though.
“Nah.”
“Alright, we don’t need BIGINT in the ‘balance’ column.”
A bit of an aside, but the richest person I know (as in buys multi-million dollar cars on a whim and has many many of those) says his credit score is pretty mediocre because he's never had a loan. I'd thought having gazillion dollars in the bank would give you a good credit score but guess not.
