I grew up in North Georgia where the rural and ghetto areas are poor, not middle class, and everyone has a subprime loan. It usually goes like this: you run up your shitty interest rate credit cards on car repairs to get to work, you come across this refinance service that will pull your 3-5 1000$ credit cars into one payment and reduce what they're paying by 80-200$. They're excited and don't even notice that it's 20% interest for 5 years. They realize after a while but they just say that they'll refinance once their credit score has improved after building their credit. Their car has another issue and now they have more credit card debt and a subprime loan.

I know you think it's mostly middle class but I grew up in dirt poor white ghettos and I could write a book on how many people make this mistake. Surviving sucks.
