Actually, if you go and toss out approximately 50-percent of medical procedures, limit people on replacement knees/hips to only those with the right health/weight, and toss on a massive cigarette/alcohol tax....you could probably fund this (the cost would decrease from the $400 billion). Course, go explain to folks that a single pack of smokes would now cost $12 (up from roughly $6) and see how aggravated they will get.
Sounds like when Sarah Palin pointed out the Death Panels, heh heh
