Everything, let's start over again. We have a pretty damn good blueprint on our hands.
Force an election where none who has served already can run (no incumbents), or just pick 435 + 100 names out of the phone book. Those elected/selected get their last month's salary + inflation. Can serve one term only and then back to where you came from. No bennies, just the extension of what you had before your term. NOTHING extra after you leave.
Now, this is what I call a service to your country.
Abolish all laws as of some future date, and then before that happens, force a vote on all of them. The obviously good/productive ones will pass over and over. Pork and socialist crap will fail every time.
