Name one successful central government. They all revert to cronies in power while the working stiffs pay for their luxurious life-style.
That's their exact purpose. They don't revert, it's not a byproduct or side effect. It's the intended goal disguised as public service.
Start with an amendment that states that senators and Congressmen must stay in their districts continually while congress is in session and do the business of government via electronic means. No parties, golf games or back door shenanigans. Make it difficult for those who would buy off our elected officials As they are spread through 50 (57?) states.
