I'm not saying it should be a jobs program. I was pointing out that the impact would be far greater than doctors.

I think the point that you are missing in the article is that for any company offering medical services, Medicare/aid is subsidized by other revenue. That is, from the companies perspective, it is offered at a loss. If that subsidization goes away, the company can no longer afford to offer that service. The economic impact of such an event would be massive, and a serious proposal requires far more detail than hand-waving.
