One of the main problems with modern American government is Congressional deference to the "expertise" of lobbyists when writing bills which eventually become laws and career bureaucrats when filling in regulatory gaps in such legislation. The power these unelected people wield will no doubt be increased exponentially when roughly 1/3 of Congress is in a lame-duck term and finds itself accountable to no one (and looking for a job, perhaps with a lobbying firm). Don't get me wrong. The idea of term limits and citizen-legislators returning to private life once their service is up is not without merit. I just don't think doing so through an Amendment to the Constitution would be helpful in the way many supporters assume it would.
