Does this include discretionary spending? I feel like that's pretty essential to understanding exactly what's going on... Mil-spending would look a lot more massive, I believe.
There are dozens of sites breaking down the spending (this is just another attempt at visualizing the data). A quick search led me to http://nationalpriorities.org/budget-basics/federal-budget-1... where you can find discretionary spending separated out on its own.
But I mean, my understanding is that there is un-allotted money the government is willing to spend, beyond whatever budget they approve. My understanding was that, in particular, the military budget increases dramatically under these mechanisms.
Also - Social Security should also be separate, really, it's a trust fund with a very specific money - if we turned Social Security off tomorrow, it isn't like the money collected could go elsewhere. Money collected into that fund & being spent into that fund should not be able to be reallocated elsewhere.
