Mitts's model is not reducing costs because it still relies on the profit driven private sector. Whereas, the highest ranking and most efficient health systems on the planet, are all single payer or completely government owned.
The best ranked health system on the planet (Switzerland), is still 2 to 3 times cheaper per capita than our model.
If our model worked so great, then surely at least one developed nation would emulate it. Think iPad and iPhone here.
