First of all, we have to remember that investment depends on many factors that are changing. For example, there was a major recession in 1990 to 1992, and that caused investment to decline, caused GDP to decline and caused a huge increase in unemployment, part of which may have been contributed to by some of the public policies at that time, but we have to remember that.
The main point is that when I did this estimate, it was based on keeping all other factors constant. Now, of course, if there are other changes that are going to occur, then what will actually happen to GDP and everything else will vary, but this is what economists do; they isolate the factor. My main point is that you have to be realistic. The capital gains tax increase will have an impact on GDP and on employment. The number isn't huge, in my view, but in fact, we don't even.... The number I did not include was the loss in tax revenues as a result of the reduction in GDP, so actually, to get back to the earlier question on that, I think we have to remember that the total revenue impact is actually not just looking at the capital gains revenues that are raised.
