First off, it's not a social credit score, it's a financial credit score, we're not talking about the system China has for it's citizens.

As with many of these deep dives on Americanisms, what you've found is generally worst case scenarios and also not universally applicable. Some states have restrictions on what your credit score can be used for and how it can impact you, car insurance and rentals being a prime example.

Also, by simply having a credit card (and not using it!) and not having any lapsed debts (collections or reported unpaid bills) you will easily have a score in the mid to high 700s. If you carry a balance month to month but regularly make your minimum payments you will have a credit score in the low to mid 700s. Hell. my wife had 5 bills in collection and still had a 650 before I met her.

As far as credit score applicability, it's often referenced by businesses as a measure of risk. If you have a 650 instead of a 750 your car insurance might be higher because your risk of payment is higher, but we're only talking about 10-15% more per year (US south east). Same with with rental, if you have a bunch of bills in collection or default your score will be bad, but a rental provider will be less willing to provide you service if you have a history of not paying your bills. You should still be able to find a place to live, but it will likely be more limited (for example if you have a 400, but not if you have something like a 650) or you may have a larger security deposit.

Overall your credit score likely won't be an issue 95% of the time, but if you habitually don't pay your bills then your score will go down and businesses that check your score won't want to do business with you. I can't make this clear enough, you have to be deliberate in your actions if you want your score to be low enough to cause a problem. My wife had $15k in student loans, $10k in credit card debt, and 5 unpaid bills that had been sent to collections and she still was in the 600s. The score system exists for a reason, I would argue that it should be a bit more forgiving, but the reason it exists is fair.

Non US citizens might have trouble relating to this, but people in the US take blatant advantage of systems a lot of times. I have a coworker that moved for a new job, but he didn't want to sell his house because he got it at a good rate and time. He listed his house for a decent rate and his first tenant stopped paying after the second month. He waited until 4 months hadn't been paid to take them to court and it took another 6 months to have them removed. Just before they were going to be escorted out by the sheriff they paid him the entire back rent in cash to try to prevent the eviction (they had the money the whole time!) After they were evicted he reached out to the local municipality for the water account and they found out the tenant had bypassed the water meter (basically they were stealing). The municipality then said he had to pay to fix the bypass, penalized him for the stolen utilities, and said that for any future tenants he would have to keep the account in his name rather than having the tenants file it.

American credit score systems suck, but they are generally fair and they prove themselves necessary because a certain percentage of Americans seem to have fundamental problems with following common and decent rules of this world.

I just read an article the other day that said Gen Z has the highest rate of credit card fraud ever seen in US history. As a group they just don't see any issue with ordering something online and then saying it never arrived and reversing the charges. I'm all for saying fuck the system and down with corporate interests, but it's hard to have a functional modern society that casually commits fraud and theft.
