It's worth asking, "who's corruption"? I highly recommend the book "Extortion: How Politicians Extract Your Money, Buy Votes, and Line Their Own Pockets" ( http://www.amazon.com/Extortion-Politicians-Extract-Money-Po...), which along with many things I've observed for a long time (e.g. the path and timing of Microsoft's travails, not to mention many of the details of a trial so bad the appeals court removed the trial judge while ratifying too much of his work), makes a compelling case a lot of this is a protection racket.

"Nice company you have here, would be a shame if anything happened to it...."

Unfortunately that also makes them sort of "too small to extort"; there are some very good reasons Dodd-Frank enshrined the "too big to fail" institution concept. I've only read some of the material on that bill in http://www.amazon.com/Extortion-Politicians-Extract-Money-Po... but I bet when I get to the details that's part of the reasons.

Jailing is only something ambitious DAs and Attorney Generals want to do; milking firms is where the money is for those already politically established.
