There are 1,300 competing providers of health insurance. And Roll Call's Morton Kondracke notes that the 2003 Medicare prescription drug entitlement, relying on competition among private insurers, enjoys 87 percent approval partly because competition has made premiums less expensive than had been projected. The program's estimated cost from 2007 to 2016 has been reduced 43 percent.

Some advocates of a public option say health coverage is so complex that consumers will be befuddled by choices. But consumers of many complicated products, from auto insurance to computers, have navigated the competition among providers, who have increased quality while lowering prices.

Although 70 percent of insured Americans rate their health care arrangements good or excellent, radical reform of health care is supposedly necessary because there are 45.7 million uninsured. That number is, however, a "snapshot" of a nation in which more than 20 million working Americans change jobs every year. Many of them are briefly uninsured between jobs. If all the uninsured were assembled for a group photograph, and six months later the then-uninsured were assembled for another photograph, about half the people in the photos would be different.

Almost 39 percent of the uninsured are in five states -- Florida, Texas, New Mexico, Arizona and California, all of which are entry points for immigrants. About 21 percent -- 9.7 million -- of the uninsured are not citizens. Up to 14 million are eligible for existing government programs -- Medicare, Medicaid, SCHIP, veterans' benefits, etc. -- but have not enrolled. And 9.1 million have household incomes of at least $75,000 and could purchase insurance. Those last two cohorts are more than half of the 45.7 million.

Insuring the perhaps 20 million persons who are protractedly uninsured because they cannot afford insurance is conceptually simple: Give them money -- (refundable) tax credits or debit cards (which have replaced food stamps) loaded with a particular value. This would produce people who are more empowered than dependent. Unfortunately, advocates of a government option consider that a defect. Which is why the simple idea of the dependency agenda cuts like a razor through the complexities of this debate.
