I'm not an accountant nor a cpa, but I understand finance some in my business as a financial planner. Tax revenues go up when taxes are low. This has happened always. It is true that you cannot tax your way out of debt nor to prosperity.
Spending is the root of all debt, period. Just remember that the war is sucking up billions, creating this debt. Obama wants to trade the military debt for local spending, so don't expect the Democrats to do anything but continue the debt, reduce your freedoms, and they WILL take your guns away.
