“First, ObamaCare’s restraints amount to nothing more than ratcheting down the price controls that traditional Medicare uses to pay health care providers. Structuring Medicare subsidies in this way — setting the prices that Medicare pays specific providers — makes it very difficult to lower those prices, because the system itself creates huge incentives for providers to organize and lobby to undo those restraints. As I explain more fully in this op-ed from September 2010, Medicare vouchers would change that lobbying game by reducing the incentives for provider groups to expend resources in the pursuit of higher Medicare spending. That gives the Ryan-Rivlin restraints a much better shot at surviving.”
