The latest reports from Massachusetts warn that with just seven weeks left until the state’s mandate for individual health insurance goes into effect, more than 100,000 residents have failed to buy the required insurance. That represents nearly 20 percent of the state’s uninsured population and more than half of the uninsured with incomes too high to qualify for subsidies.

According to insurance industry insiders, the plans are too costly for the target market and the potential customers — largely younger, healthy men — have resisted buying them.

How could anyone know that an individual mandate for health insurance would be unenforceable? Oh yeah, we told them.
