So, do you have anything else? Let me give you some of what I have;
Consider the $100 billion in personal tax rebates that were issued as part of a broader economic stimulus effort in 2008. Only about one-third of the total amount was spent. A University of Michigan study in December 2008 concluded that these rebates provided “little ‘bang for the buck’ as economic stimulus.”
Similarly, a series of tax cuts in 2003 fell far short of targeted job growth. The Bush administration claimed the tax cuts would create 1.4 million jobs, in addition to some 4.1 million jobs expected to be generated over an 18-month period. But EPI tracked the initiative and found that not only did the additional 1.4 million jobs not appear, but the 4.1 million jobs that had been expected without the tax cuts never materialized either. By the end, the economy only saw an additional 2.4 million jobs added to the economy.
Tax cuts won’t create jobs
So what did John Q. Taxpayer get for all that tax cutting? Certainly not jobs, but instead a huge deficit bill now coming due. Nonetheless, the debates in Washington now still focus on more tax cuts in 2011. So long as that's the focus, the U.S. unemployment situation will continue to stagnate or worsen.

Tax cuts may comfort the comfortable, to quote consultant Robert Shrum, but there’s not a convincing case that they result in new jobs.
