But a necessary one if we're ever going to get single payer.
More and more companies will drop health care coverage because it sucks for them to administer it. Not only is it expensive, its a minefield. Once the middle and upper managers get dropped and have to shop on the exchanges then we'll probably see a bigger push for single payer.
Those folks have been on the health care/insurance gravy train and once they get booted off their pretty decent, employer-based health plans and have to pay full freight on the market (without a subsidy since they'll make too much) that's when the fuss will happen.
But the short term pain is going to be tough for a while.
