Many US hospitals try to collect medical debt by suing patients to claim part of the value of their homes. It is perfectly logical, in an economy which values profit for the rich over the lives of everyone else.

Note how Belk's medical insurance required him to go back to the hospital company that had sued him before. It did not cover treatment anywhere else. That is a common nastiness of private medical insurance in the US. A national medical system would not do that. It also would not put patients into debt for failure to be rich.
