What system/trade, public or private, doesn't shun whistleblowers?

We would all like to say "we don't!", but the truth is that we're all doing it. Nobody wants to hire someone who might cause trouble. Of any kind. For an employer, all bad PR reflects on you. So you hire people who won't give you any bad PR.

To try to blame this problem on any one thing("socialized" health care, the government, the health care industry in general, etc) is ridiculous. We all do it.
