Should politicians take a lifelong, legally-binding vow of poverty? A vow tying them to a state-provided one-person bare subsistence income from the beginning of their elected term until the end of their lives, with strict restrictions on gifts they are allowed to receive from others. This would cut corruption down dramatically; there's no $500k/yr industry job waiting for them after their term. Once you take away material gain, the politicians would have to serve only because they feel they can improve things. Of course, it would only be practical above a certain level; it's probably not practical to give every minor official a lifelong stipend, even a small one. So, it would be applied only from the level of town commissioner on up. And, there would be no ban on politicians taking later jobs for their own enjoyment, so long as they don't get to keep any income above their minimum stipend.
