The endgame?
…the exchanges will get much bigger over time. Part of what’s going on in the United States is that the employer-based health insurance system is slowly unraveling. Both the House and Senate versions of reform consist not only of using exchanges to cover the currently uninsured, but also using exchanges to construct a kind of safety net so that as employer-based insurance continues to unravel, people will land softly in exchangeland rather than crashing into the rough ground of the current individual insurance market. The Senate bill will slightly accelerate the decline of employer-based insurance by slowly phasing out the tax subsidy for such insurance.
That is Matt Yglesias, here is more. Of course if this is true — and it may well be — the composition and nature of the exchanges means everything.
