WHAT TO DO WHEN OBAMACARE UNRAVELS:

The unraveling of the Affordable Care Act presents a historic opportunity for change. Its proponents call it “settled law,” but as Prohibition taught us, not even a constitutional amendment is settled law—if it is dysfunctional enough, and if Americans can see a clear alternative.

This fall’s website fiasco and policy cancellations are only the beginning. Next spring the individual mandate is likely to unravel when we see how sick the people are who signed up on exchanges, and if our government really is going to penalize voters for not buying health insurance. The employer mandate and “accountable care organizations” will take their turns in the news. There will be scandals. There will be fraud. This will go on for years. . . .

There is an alternative. A much freer market in health care and health insurance can work, can deliver high quality, technically innovative care at much lower cost, and solve the pathologies of the pre-existing system.

The U.S. health-care market is dysfunctional. Obscure prices and $500 Band-Aids are legendary. The reason is simple: Health care and health insurance are strongly protected from competition. There are explicit barriers to entry, for example the laws in many states that require a “certificate of need” before one can build a new hospital. Regulatory compliance costs, approvals, nonprofit status, restrictions on foreign doctors and nurses, limits on medical residencies, and many more barriers keep prices up and competitors out. Hospitals whose main clients are uncompetitive insurers and the government cannot innovate and provide efficient cash service.

We need to permit the Southwest Airlines, LUV -0.26% Wal-Mart, WMT +0.40% Amazon.com AMZN -0.06% and Apples of the world to bring to health care the same dramatic improvements in price, quality, variety, technology and efficiency that they brought to air travel, retail and electronics. We’ll know we are there when prices are on hospital websites, cash customers get discounts, and new hospitals and insurers swamp your inbox with attractive offers and great service. . . .

Health insurance should be individual, portable across jobs, states and providers; lifelong and guaranteed-renewable, meaning you have the right to continue with no unexpected increase in premiums if you get sick. Insurance should protect wealth against large, unforeseen, necessary expenses, rather than be a wildly inefficient payment plan for routine expenses.

People want to buy this insurance, and companies want to sell it.

Unlike ObamaCare, which is the reverse.
