I agree that we don't get a good return on the taxes we pay. But, defense spending is about 1/6 of the federal budget at around 3% of GDP. For comparison medicare/medicaid combined is about 5% of GDP. Apparently France spends 4% of GDP on healthcare total, not just for old people. I think the biggest problem with our system is not necessarily that defense spending is so high, but that our healthcare system is so inefficient.
