Contrary to what some Republicans say, we didn't have a free medical market before Obama came to power. We had a system that limited competition through occupational licensing, FDA rules and other government intrusions, while stimulating demand through tax-favored employer-based "insurance," Medicare and Medicaid. If we want affordable and cutting-edge health care, there's only one approach that will work: open competition. That means eliminating both bureaucratic obstacles and corporate privileges. Only free markets can give us innovation at the lowest possible cost.
