I don't remember whether I commented on this when the Obama Administration released its budget last year, but I'll point it out this year - as Ezra Klein comments, the U.S. government continues to be basically a big insurance company with a large army:
And the work my agency should probably be counted as "insurance" as well, though we're in the "everything else" category above. So, yes, the elderly and the military eat up 2/3s of the federal budget, leaving not much for the rest of what citizens want the government to do.
Also, on a personal note, I'm about to get on a plane to Europe, so there will likely be no posting for 1.5-2 weeks. In the meantime, check out the archives, and take care of yourselves!
