Oh dear, an economic/political rant on Slashdot...
The US cannot go bankrupt. We are a sovereign nation that issues its own currency. Get over it.
This "waste" creates jobs and spurs R&D. It inflates our money supply at a time when the economy is sluggish, and boosts the private sector. Why are people complaining?
If you think taxpayers are funding this "waste", you're wrong. Taxpayers pay taxes, that's it. Unless the budget is balanced there's no association between federal spending and revenue, they are just two different dollar totals on the books. (And I'm not advocating balancing the budget simply to curtail spending.)
If you think our children (or grandchildren, great-grandchildren etc.) are going to have to pay off this debt, that's also incorrect. Federal debt is always serviced by issuing more currency.
I'm not saying the government can spend without limit, but there are no hard limits. The practical limits are set by inflation rates and real resources. At present, real resources are abundant and inflation is low. So let's raise spending. If we reach 99% employment and inflation sets in, we can curtail government spending.
This isn't solely my view--lookup Modern Money Theory. Many economists understand these principles of a fiat currency. Few politicians do, unfortunately, and they like to throw around words like "debt" and "waste" without understanding their meaning.
