They badly need a "new idea" that is workable and of which most will approve and benefit from (and the economy, too).
The existing tax system will certainly not continue as it's on its last lega and surely you don't trust Congress to "fix" that satisfactorily by more tinkering as has gone on for almost 100 years now.
Join with us is putting a tax law in place that will offer us some protection against having both at the same time while amending the Constitution. Help pass the Fairtax.
