That will be the next problem. The numbers for Obamacare on the federal funding side only work for a finite number of people. And only by taxing for ten years and having five years of benefits. Assuming static employment, when the number of employers not providing coverage goes up, the penalty is $2500 a year, which is a fraction of the required subsidy for the new Obamacare recipient.
This only considers the government funding portion, not whether the insurance companies remain viable with all the last minute changes the administration has enacted.
