We also have 30,000 retirees under the age of 65, 128,000 employees in our local school systems, and 110,000 employees in local government, all of which presents strategies even more economically attractive than the thought experiment we just performed. Local governments will find eliminating all coverage particularly attractive, as many of them are small and will thus incur minor or no penalties; many have health plans that will not meet the minimum benefit threshold, and so they’ll see a substantial and unavoidable increase in cost if they continue providing benefits under the new federal rules.

Our thought experiment shows how the economics of dropping existing coverage is about to become very attractive to many employers, both public and private. By 2014, there will be a mini-industry of consultants knocking on employers’ doors to explain the new opportunity. And in the years after 2014, the economics just keep getting better.

The consequence of these generous subsidies will be that America’s health reform may well drive many more people than projected out of employer-sponsored insurance and into the heavily subsidized federal system. Perhaps this is a miscalculation by the Congress, perhaps not. One principle of game theory is to think like your opponent; another is that there’s always a larger game.
