Without the exchanges, the death spiral seems almost assured. The amount of work required to find a policy, figure out your subsidy, buy coverage and file the paperwork will be very high. And it’s unlikely that folks who can’t even be bothered to go to ehealthinsurance.com right now will do it. The Affordable Care Act made the task of signing up young healthy people on the exchanges even harder with its much-loved requirement that companies allow kids to stay on their parents’ policies until they’re 26, which took millions of potential buyers out of the pool. The ones who are left are going to be disproportionately poorer and less well educated than the middle-class offspring who can get cheap insurance through mom and dad. There’s a reason that virtually every person you’ve seen written up in an article as they tried to get insurance at a community center or clinic is some combination of over 55, retired or afflicted with a serious chronic condition.

Once the death spiral happens, it’s very difficult to recover from. That’s why if the exchanges don’t work soon, we need to hit the reset button and try again next year. This will be very, very difficult: Insurers are already selling policies under the new regulations, and those regulations have driven up costs for existing buyers. People who have been counting on being able to buy insurance through the exchanges will have to spend another year without. And of course, it will be politically embarrassing. But it will be even more politically embarrassing to get to December and find out that we have commanded millions of Americans to buy insurance on a system that doesn’t work. And it is not a good bargain to cover some people now, but in doing so, to make insurance unaffordable for millions more in a few years. If we can’t launch the system correctly, then we need to wait until we can.

In the private sector, this system would already have been rolled back, probably less than 48 hours after it was rolled out. The government has more time, but not that much more, because every day they wait adds to the chaos that will occur if they have to pull the plug in December.
