It may be radical, and I wouldn't say I'm advocating it, however, the United States was formed based on John Locke's Social Contract Theory. In layman's terms, Locke states that if a government violates the rights given to it by the people, the people have a right to abolish it and start a new government.
I think that may be extreme at this point, however, I think the only way to stop us from spinning out of control is to STOP CAREER POLITICIANS. When your main goal is to be reelected, you aren't doing your job. If we could put term limits on Senate and House seats, we could make politicians concentrate on governing, not reelection.
Of course, the people that would need to make this decision are the same ones who are making political careers.
