There is no amount of tax and regulation reductions that is going to stop businesses from leaving the US. If there's a qualified workforce available somewhere else that does the work for a tenth of US wages, businesses are going to leave no matter what. I don't see what tax reductions can offset that.
In any case, the US plummeted the world's economy through lack of regulation and oversight, so I don't see how dismantling the Fed is going to help overcome that, in any way. An overhaul of the Fed might be in order, as the financial markets continue to do the crap that got the giant recession started. Wholly removing the one financial federal regulatory body the US has seems insane.
