This thread is in the wrong section. Even though that image is useful in explanations, it is outdated. The national debt is above $19 trillion and there is no sign of stopping. It is actually becoming quite ridiculous.

With or without the war machine chugging away, fixing the US' debt is a massive challenge and many governments are going to have to work to spend basically nothing and slowly pay off their other campaign promises.
