In response to your points:

1. Public service was never intended to be a career. If you stay in DC too long, you forget what "real life" is like. Treat public service like a stint in the military: you can go back to your old job after your term.

2. Replace the 13th Amendment, which was interrupted during the state ratification process by a war. The original 13th made it illegal for lawyers to serve in Congress. We need that to put common sense back into Congress.

In addition to term limits and barring attorneys, lobbyists should be outlawed. You want to give a Congressman information about your company/product/idea? Send them a letter. They'll get back to you if they're interested.

Public funding of elections and no private money allowed. And shorten the campaign times to 90 days.
