The evidence shows we could spend less and deliver more within the scope of healthcare delivery (this piece). We actively choose not to. The Pentagon hasn't passed an audit eight years in a row, I hear little that "we cannot afford to keep funding the military at these levels and with such inefficiency."

I don't want to sound like I'm fundamentally arguing with you, because if I could swap our system with Germany's I'd do so in a heartbeat. But (a) the "money that should be going into health care and education is going to military" argument is highly rebuttable, so I'd be careful hanging my hat on it, and (b) everybody, literally everybody (except the AMA) agrees we're spending too much on health care --- the problem is that money goes to practitioners, so it's very tricky to talk about clawing it back.
