Obviously, certain circumstances can cause someone to need to use credit card debt to shelter/feed themselves and their family. I would be willing to bet the vast majority of credit card interest is not caused by essential needs.
We first need to start changing our values to be more financially conservative. Once that happens and voters start making these values apparent to politicians, they can take actions that will help reduce costs for citizens.
Think about the economy! If political leaders were wanted the elderly to sacrifice thier lives to COVID "for the economy", then the overspenders have no chance of being save from bankruptcy. The purpose of a system is what it does, and the American one moves money upwards.
Logically, this question must be answered with sincerity before blaming financial illiteracy.
Really, an hour on Google will give you all the information you could need to manage credit cards. It's not complex.
My public schooling in a podunk county TN had no component for financial management.
Even so, you assume that such education exists in a vacuum. It does not. It runs counter to a deluge of culture and advertising that tries to induce people to go into debt the moment they are able to pass a credit check.
Economics was a de facto personal finance class, which was nice. It refused to admit that because "economics" looks better on a transcript than "personal finance". This meant it was a rarely taken elective for folks who wanted to look good to colleges.
Calculus was also an elective for folks who wanted to go to college, which was notoriously more difficult but more popular in spite of this. People not going to college weren't taking either one.
I believe grandparent that compound interest wasn't taught anywhere in a small public school. A lot of those schools don't even offer calculus.
I went through the U.S. education system in 8 different states in schools in poorer areas, and even then, the education was sufficient to understand the concept of not spending money you do not have.
Set the thing to auto pay the balance every month, and do not spend more than you earn. I expect that much from 95% of the population that has had the opportunity to learn how to read and write.
