As a bonus, public spending on healthcare in the US is matched by massive private spending, being responsible for most bankruptcies and foreclosures and tying many people to wage labor who would rather be entrepreneurs.
We know that healthcare with better outcomes than current ones doesn't have to be expensive. That money has been wasted. There's no established cost for endless multifront war other than our own historical experience, so it's hard to know if money is being wasted there.
We do know that we would have been running surpluses through the recession and into the foreseeable future if our healthcare system had the same costs as other systems, and wasn't a pile of rent-seeking, kickbacks, monopoly and artificial scarcity, and rats.
