Our Framers were not Utopians. They were practical men experienced in self government. Madison described the strengths and reasons for a House as well as possible corruptions.
He asked, “It is possible that these may all be insufficient to control the caprice and wickedness of man. But are they not all that government will admit, and that human prudence can devise? Are they not the genuine and the characteristic means by which republican government provides for the liberty and happiness of the people? Are they not the identical means on which every State government in the Union relies for the attainment of these important ends?”
So yes, all men and governments can be corrupted. The House is no more nor less corrupted by its structure than any state legislative body.
That may well be true but the fact is that if we the people exercised a little more supervision of our employees in government there would be FAR less corruption!
Perhaps we are beginning to see that with the advent of the Tea Party movement. I certainly hope that to be the case!
