the deficit and the current economic crisis are not one in the same.
Dean Baker:

To be sure, the tax cuts were a bad use of public money. As we know, they disproportionately went to the wealthy. This money could have been much better used rebuilding infrastructure, promoting renewable energy and conservation, or even as tax cuts oriented more toward middle class and moderate income families.
However, the tax cuts were not the economic disaster portrayed in the Democrats' attacks. The deficits were not especially large in the Bush years. And, the economy needed deficit spending to get out of the recession caused by the collapse of the stock market bubble. Furthermore, the trade deficit caused by over-valued dollar inherited from the Clinton Administration, necessitated some alternative source of demand, like a budget deficit, to bring the economy anywhere near full employment.
Unfortunately, the political elites' fixation on the tax cuts and the deficits led them to ignore the economy's real problems.
The housing bubble grew to ever larger proportions, eventually reaching a point where its collapse would lead to the sort of recession that we are now experiencing.
<...>
Tax cuts for the rich are not good economic policy because they needlessly add to the deficit, but they did not contribute to the economic crisis.
