These plots show more details. Figure 1 shows the components of GDP, Figure 2 shows the private sector gross vs. government funding and Figure 3 shows GDP vs. govt funding.  Government funding has been increasing all the time but the peak of GDP occurred in 2007, fell in 2008 and 2009 and has risen in 2010. In general the private sector gross is four times government spending. The decrease of GDP may be attributed to the money wasted in wars and due to less employment.
