? The people providing healthcare today, are as you described, except they have huge, fat, ridiculous margins. They commit what would be point blank fraud in any other country, all day, every day.

Walmart is a massive machine that operates by design on thin margins. They force out surpluses all the way down the value chain and in their own operations and instead of selling at max margin, they sell at low margin, because they know they win in the long run.

Walmart might be exactly what you'd invent if you wanted to provide healthcare at the best price to the most people. There's the possibility they could be more efficient than any system anywhere as most public systems are full of fat as well ... certainly more than the 5% or so margin Walmart might take in.
