I don't understand how that link shows student loans are a driver of inequality. Black people on average have a higher student loan debt because on average black people are poorer than white people in America. If black families are poorer than white families, it generally means they will need to take out a bigger loan to afford college.
It's almost as if you shouldn't be able to take on near unlimited non-default-able debt for something that is nearly worthless.
These people were put into a debt trap at 18, not saved by the government.
It's also interesting that finance is left out of most high school curriculum right before people are signing up for the second (and increasingly the first) most expensive purchase of their lives.
