While I haven't looked into it I expect that suicides increased during the subprime meltdown, also that many turned to a life of crime with some committing murder.

Yet none of the bankers have gone to prison.

I was once a suicide hotline counselor. People have many reasons to commit suicide. In every case that I know about it is something that can be overcome if one can find a way to survive. A man once jumped off the golden gate bridge. As he fell, he realized that in reality he had no problems. Well, one problem.

He had just jumped.

However he was one of the very few to survive.
