tax revenue > [interest+medicare+SS+defense] (although civilian defense were furloughed). Adding Fed pensions or income security would put it in deficit.
What the heck is income security?
You are missing the point. Forget all other spending. The revenue that comes in has to cover, and does indeed cover, the interest on the debt. The US Govt pays that bill first. It always has. Always will. It is like a family paying the mortgage first THEN the other bills.
