Congress should be elected for no more than 2 consecutive terms. After which they can not be hired as lobbyists, they can receive no future benefits after office.
Why is this important?
The major dysfunctionality of government is the good old boy network of politicians who run this country for their own profit. If they had a two term limit then they wouldn't be able to wield the power they currently control. The intent would be for them to do what is in the best interest of the people and not the corporations that currently run our government.
