I haven't had a chance to watch the latest John Oliver show, but generally I would imagine that I know where he's headed with talk about the federal budget. The idea of getting rid of PBS and NPR and, as someone earlier already said, nickel-and-dime your way towards balancing the budget is just foolish. Even if you somehow could pull it off for one budget (impossible, but just for the sake of argument), it wouldn't be sustainable in the long term, as the costs of other, more expensive items would continue to go up and you'd be left with fewer and fewer places to cut around the edges.
If Trump were actually serious about getting rid of the waste, fraud, and abuse and about getting all of the spending under control, he'd look to the Pentagon and the Department of Defense. We spend more on defense and the military than the next 7 or 8 largest militaries in the world combined. In a world where combat is more nuanced and doesn't necessitate having vast armies, but rather more highly specialized, yet smaller, units in addition to cutting-edge technology and drone warfare, the budget should be shrinking, not expanding in the way that Trump proposes it should.
