Three plots are shown in this blog. Here are more plots derived from US Gross Domestic Product data from years 1969 to 2009 available at
plotted in many ways. Figure 1 shows the various components of GDP, Figure 2 shows government spending and GDP keep in step and are roughly proportional to each other. Figure 3 shows that Govt_spending is proportional to the rest of GDP which is the private sector Gross Product. This plot shows that government spending is one quarter of the private sector gross product. In this plot taxes have not been included. If taxes are removed From Government spending, the curves will still remain proportional given that taxes are a small part of government spending. We can conclude that reduction of government funding (the imagined debt crisis) will reduce both GDP and the private sector gross product.
