I always assumed credit scores were an integral and historic part of the American financial system.
They were not, they are very recent，most of your parents didn’t have credit scores growing up, and as you can probably tell or at least intuit, it’s mostly just a b******* scheme for those with capital to accrue more capital by invading your privacy.
Exactly. It is potential debt and it goes against getting new loan/debt from banks. No matter if you have used the credit card or not. The banks look at the available limit on an your credit cards or available credit and view that as debt when they calculate how much they can loan you.
