Your thoughts on a Non-Constitutional Legislative group created to "fast track" issues?
Sounds exactly like China's government. A small, fast steering committee that can quickly decide on "issues" without endless discussion or filibustering.
It would be more efficient, and prevents petty ideological issues from getting in the way. Democracy is only a shill, these days, no matter what you vote everyone knows where the government is going. After all it's the same guys sponsoring both political 'sides'. So why not abandon it completely...
Desirability aside, I doubt the US could out-do China in its own game.
