Gallup did a poll about wasteful spending, and ended their writeup on the results with this:
Over the last 30 years, Americans have become increasingly likely to see all levels of government as wasting the money they spend, and now the public believes the federal government wastes more than half of the money it spends. It is not clear whether Americans believe government wastes money because it spends on programs they believe are not needed, or because it does not spend money efficiently on programs, whether needed or not. Also, it is not clear whether Americans believe money is wasted more on discretionary government spending, or more on defense, entitlement programs, and interest on the debt — which make up the bulk of federal government spending. (emphasis mine)
Well, why didn’t you just ask?
