The "current tax code" has been in existance through quite a few rounds of solid economic growth. The very suggestion that our economic troubles are because of our tax code is absurd. Improving our tax code could help economic growth, but the real problem is government regulation and Obama "stimulus" that is destroying jobs rather than creating them.
You apparently haven’t noticed how much the tax code has changed since the last downturn. Can we say Obamacare? I still say that Obamacare is the biggest strangle on our economy right now.
