Labor costs are usually a business' #1 expense. Labor costs are much, much lower in other countries than they are in the US.
Regardless of what you think the cost is, here is the data. (and if anything corporate tax rates are lower now than in 2002)

As you can see, the US is around 30% lower than the weighted average and lower than nearly every country on the list. Corporate taxes are not our problem.
I agree. Corporate taxes are not causing small/mid businesses to not hire, expand or grow. Income taxes are another story completely but thats for another topic. I am not sure about the Goldmans of the world but it seams to me they have gotten plenty of help from Uncle Sam lately and are pulling in record profits so it obviously can't be that big of a problem.
