Consider: 27 million people are covered by health insurance purchased directly, i.e. outside employer-based plans. The average cost of an insurance policy with family coverage in 2009 is $13,375. A married couple with a median family income of $75,000 who choose not to insure would be subject to a fine of 2.5 percent of that $75,000, or $1,875. So the family would save a net $11,500 by not insuring. If a serious illness occurs — a chronic condition or a condition that requires surgery — they could then buy insurance. Since fewer than one family in four has annual health-care costs that exceed $10,000, the decision to drop coverage looks like a good bet. For a lower-income family, the fine is smaller, and the incentive to be uninsured is even greater.
