Getting the government completely out of the medical and insurance fields would return medicine to rationality and come as close as possible to universalizing access because the costs would be drastically lower. Insurance would become insurance again, which it has not really been since FDR. It would be cheap and mostly only cover large expenses like heart and brain surgery. Everything else would fit into normal household expenses. There would be, however, no electoral and financial benefits for politicians so I am sure it cannot possibly be done.
