Something something privatize the earnings socialize the losses.

A good part of government's job is to limit risk so that those most at risk don't suffer. Speed limits exist to limit risk. Drug laws exist to limit risk. Bank regulations exist to limit risk. SEC laws exist to limit risk. In a system with safety nets (unemployment laws, bankruptcy laws, welfare, food stamps, subsidized housing programs, etc), there must be some limits to prevent abuse of these programs from undue risk.
