The overall federal budget is unsustainable by almost all projections. Social security is the single largest budget item. Essentially you can think of the federal budget as being social security, medicare, the military, interest payments on the debt, and a little bit of other stuff. You could cut everything else but those items, and, over the medium term, those budgets are still not sustainable.
