It's rotting from the bottom-up. The collapse has already happened for the lowest income people, and in regions where incomes are predominantly low. If you don't have enough money, or a reliable car, or the ability to take time off work, that means you simply don't get professional medical service. For a lot of people, medical services have effectively stopped existing in the USA; you just ask your friends and family what sort of remedies you can buy at a corner drugstore, and do what you can. We're at the beginning of the process of drugstores starting to pull out of certain areas as well, which will basically just leave local corner convenience stores as the last place where you can acquire actual medical supplies.

This collapse is slowly creeping up the income ladder. It's been hitting middle income people hard for awhile, who are regularly foegoing some important medical treatments. It's even starting to creep into the lower eschelons of high income people, who are being hit long waits for scarce services, and are also at risk for bankruptcy for some medical issues.

It's a good example of how collapses happen. Not overnight, dramatic collapse of a structure. More like gangrenous flesh slowly rotting away until there's nothing left. The collapse of US medicine comes in the form of "guess I'll just die"
