Another Difficulty with Implementing Single Payer Health Insurance in the USA

Another Difficulty with Implementing Single Payer Health Insurance in the USA is that if economists like Milton Friedman are correct the states are causing much of the high cost. Worse with the federal Government already paying for 50% of health care, state and local politicians have an incentive to push up medical costs in their states. This will only get worse if all medical spending is done through the Federal Government.
