I think there are good people that want to serve, but they have to play the money game to survive (costs millions/billions to get elected?? What?!). Which eventually corrupts them ...
Term limits might be nice too.
I honestly and genuinely don't think that's much of a question.
I encourage you to read Lawrence Lessig's "Republic, Lost" - which talks about how the big money behind campaign financing makes average Joe's feel as if they're choosing a politician based on their will, which turns out to not really be the case. Rather, they're choosing from a select group of politicians already rubber stamped "OK" by deep pocketed donors.
A good quote (not verbatim) from the book is basically how deep pocket donors have a sense of: "Let me choose the potential candidate options, and I don't really care who wins".
So it's the "will of the people" only so far as the people's will aligns with something they have 0 control over - the intentions/ambitions of those with money - which doesn't sound much like free will.
