This is ruining America's future. That's 5M people who can't even qualify for a car loan now. The penalties for default are punishing. Even bankruptcy isn't a realistic option.
This is ruinous for these people. They'll be in their mid-30s or early 40s before they can pay off. Starting that late to build a nest egg, they'll never recover. There's going to be an entire generation that has no secure retirement plans. It will also be a baby bust. By the time they are stable enough to think about starting families, they'll be biologically incapable to produce. Nobody will be around to fight off invaders. We're seriously toast in 50 years at this rate.
