A balanced budget (no growth in debt)
Balanced budget of course, anyone who says tax cuts at this point is just delusional. What I've found from all these debates is that most people screaming for Bush's tax cuts were not the ones who benefited from it. The ones who believe that Obama "raised their taxes" in fact got a tax break from Obama. People delude themselves into thinking they are somehow in the top 1% of the population that earns more than $250k per year. They almost never do. They're lying to themselves and to others, just like "Joe the Plumber."
We actually need to raise taxes to pay off the debt, plain and simple. Spending needs to be cut IN HALF or more, and stay that way permanently.
Why on Earth would the GDP increase due to Bush's tax cuts?
I just don't see how Bush's tax cuts lead to "higher productivity and output." All I saw was disasterous malinvestment and the pending collapse of our economic system. This idea that cutting the taxes of the superwealthy somehow causes them to invest the money back into the country is a myth -- that never happened. I'd like to see some evidence that the Bush tax cuts did absolutely anything useful for our economy in the first place. Otherwise, they should have been made to expire.
