Sorry, look up Rent Seeking: http://en.wikipedia.org/wiki/Rent-seeking
Benito Mussolini was a socialist before he was a fascist. Authoritarian cute fuzzy awesome nice left wingers are still Authoritarians. Assertions that Money corrupts Politics are at a similar level of naivete as saying that Oxygen is responsible for the corruption of your favorite forest by enabling Fire.
Not that Money doesn't exist in a finding of corrupt behavior, it's one of many things that fit into that mix. Money itself is an Amoral entity.
