How medical debt became normal in the U.S.

Widespread medical debt is a uniquely American problem, with such debt totaling at least $195 billion in 2019. It was once thought that the problem was that Americans were largely uninsured, but even those with health coverage can run into problems. Over 90% of the U.S. population has some kind of medical insurance, but about 40% of adults say they have at least $250 in medical debt.
