Critics of the U.S. health care system have a litany of complaints. Some are true, but highly misleading. N. Gregory Mankiw takes on three of the latter in a recent New York Times piece. For instance, he observes:
Some 47 million Americans do not have health insurance. This number from the Census Bureau is often cited as evidence that the health system is failing for many American families. Yet by masking tremendous heterogeneity in personal circumstances, the figure exaggerates the magnitude of the problem. To start with, the 47 million includes about 10 million residents who are not American citizens. Many are illegal immigrants. Even if we had national health insurance, they would probably not be covered. The number also fails to take full account of Medicaid, the government's health program for the poor. For instance, it counts millions of the poor who are eligible for Medicaid but have not yet applied. These individuals, who are healthier, on average, than those who are enrolled, could always apply if they ever needed significant medical care. They are uninsured in name only. The 47 million also includes many who could buy insurance but haven't. The Census Bureau reports that 18 million of the uninsured have annual household income of more than $50,000, which puts them in the top half of the income distribution. About a quarter of the uninsured have been offered employer-provided insurance but declined coverage. Of course, millions of Americans have trouble getting health insurance. But they number far less than 47 million, and they make up only a few percent of the population of 300 million. Any reform should carefully focus on this group to avoid disrupting the vast majority for whom the system is working. We do not nationalize an industry simply because a small percentage of the work force is unemployed. Similarly, we should be wary of sweeping reforms of our health system if they are motivated by the fact that a small percentage of the population is uninsured.Too bad lawmakers don't understood the facts before voting on health care issues.
