First, Congress should give Medicare enrollees a voucher and the freedom to choose any health plan on the market. Vouchers would be means‐​tested, would contain Medicare spending, and are the only way to protect seniors from government rationing.

Second, to give workers control over their health care dollars, Congress should reform the tax treatment of health care with “large” health savings accounts. Large HSAs would reduce the number of uninsured Americans, would free workers to purchase secure health coverage from any source, and would effectively give workers a $9.7 trillion tax cut without increasing the federal budget deficit.

Third, Congress should break up state monopolies on insurance and clinician licensing. Allowing consumers to purchase health insurance licensed by other states could cover one‐​third of the uninsured without any new taxes or government subsidies.

Finally, Congress should reform Medicaid and the State Children’s Health Insurance Program the way it reformed welfare in 1996. Block‐​granting those programs would reduce the deficit and encourage states to target resources to the truly needy.

The great advantage of a free market is that innovation and more prudent decisionmaking means that fewer patients will fall through the cracks.
