What some people have missed in the issue is that the U.S. government hasn't done a comprehensive analysis of it's spending in 50 years. Not that cuts don't need to be made (they do) or taxes need to be raised (they might) but we have no idea where much of the spending goes. It's like they took a 100 year subscription to Prodigy (remember them?) and keep paying it year after year even though it stopped existing long ago. My pet peeve is the Rural Electrification Act and Administration that gets funding year after year. No anyplace that doesn't have electricity? (Well, that works, maybe not, but you get my point, hehehe.)
But no one in either party seems the slight bit interested in looking at the details in the budget, much of the spending of which is stuck in sub-sub-sub budgets that aren't ever considered!
