He couldn't afford to go to hospital, so never did. I was visiting from Australia at the time and was utterly horrified, having no idea the US worked like that. Now years later his shoulder is still screwed.

In a stack of OECD countries (all the other ones?) nobody has ever gone bankrupt from medical bills, because that's impossible.
