As for the unemployment rate increase after the collapse, it was actually 49%, based on average unemployment rates during the year. Compare 2000-2009, and you see the increase. A brief history of U.S. unemployment - The Washington Post
States were left with less money because of Federal cutbacks as a result of the bad economy, having to incur higher costs for unemployed and displaced workers, and less tax revenue from workers, as for just a few of the obvious reasons.
I could go on and on what were the direct results of the collapse, but it hasn't been a "zero sum game" for our country or taxpayers, by any means. It has, and is, cost us dearly.
