Compared to what other countries?
I think a lot of waste and corruption is due to winner-take-all elections. A representative that represents one party has to answer to that party. If he does not represent its interests, they will elect someone else next time.
In winner-take-all elections, you vote for your least worst option and representing one perspective doesn't as matter as much. It's easier to sell your vote to lobbyists.
But people are convinced that our elections were implemented in the best possible way, so there is a reluctance to even weigh the options.
