In a wonderful understatement, Tyler says he will file this under "Not a political equilibrium." A less restrained blogger might have gone with "trainwreck."
Steve Entin at the National Center for Policy Analysis has written on the very issue of the subsidies vs the tax exclusion. His conclusion:
Adding the subsidies for premiums and cost sharing, the family getting the health exchange policy would receive a total subsidy of $17,400, while the family receiving employer-based insurance would receive a total subsidy of $4,143.
That is a huge differential. The whole piece is here: http://www.ncpa.org/pdfs/Health-Insurance-Exchange-Subsidies-Create-Inequities.pdf
It would seem that reforming the reform is now a question of when and not if. All the more reason for the GOP to pivot away from this in the short term.
