It has been a year since my college roommate, Scott Androes, died of prostate cancer, in part because he didn’t have insurance and thus didn’t see a doctor promptly. Scott fully acknowledged that he had made a terrible mistake in economizing on insurance, but, in a civilized country, is this a mistake that people should die from?

“Website problems are a nuisance,” Dr. Gibson said. “Life and death is when you need care and can’t afford to get it.”

The Institute of Medicine and the National Research Council this year ranked the United States health care system last or near last in several categories among 17 countries studied. The Commonwealth Fund put the United States dead last of seven industrialized countries in health care performance. And Bloomberg journalists ranked the United States health care system No. 46 in efficiency worldwide, behind Romania and Iran.

The reason is simple: While some Americans get superb care, tens of millions without insurance get marginal care. That’s one reason life expectancy is relatively low in America, and child mortality is twice as high as in some European countries. Now that’s a scandal.

Yet about half the states are refusing to expand Medicaid to cover more uninsured people — because they don’t trust Obamacare and want it to fail.
