This is exactly the kind of thing I'm getting at - absolutely 100% of bankruptcies are caused by debt; perhaps 60% of them also have medical debt somewhere in there, but that may be a distraction (after all, once you're on the path to bankruptcy why bother trying to make medical payments, they're not going to repossess your lung but they very well may repossess your house).

The US has a major debt problem and the solution at some point is going to be curtailing just how much debt you can accumulate with just a signature.
