Well there may be a market for it when your family bronze plan is like $2500 per month and the gold Obama plan is $3500 per month. Nobody is gonna buy a crap Obama plan because it will be too expensive.
That's why they're sellin' em, they make a lot of money, which means the client never sees it pay off.
With regards to high cost of exch plans, it's only high cost for high income/assets folks. Either they can afford it, or have to afford it to protect their assets. An LB plan is a waste since they can afford to pay cash for care, and the premium won't protect them from BK.
