Good post, and the pat response is "vote them out". The problem with this is that the neither party really thinks this kind of corruption is a problem, and the individual pols that do can't get elected on that issue alone. That is, there's a critical "bundling" problem with modern politics: you have to accept a bundle of 100 positions, and "integrity issues" are usually pretty low. Even worse, a cynical body politic begins to perceive "integrity" as a liability, that someone with conscience and self-restraint is actually LESS capable of "winning" within a corrupt system. You've now allowed your short-term need to win to further degrade the system, which of course becomes a positive feedback loop.

(This bundling problem affects all kinds of products. When you're shopping, you pay attention to price, and everything else is secondary. In a perfect market, you'd price in the forced arbitration clause, or you'd price in the social cost of anti-competitive business practices of the vendor. But it just doesn't happen because the cognitive load is too high.)

I really miss the days when we at least paid lip-service to the idea that character and integrity mattered most in our pols. Even that system was gamed, its still better than overtly, cynically abandoning society's most laudable values.
