Occam's razor is sometimes to dull a blade. It is an gross oversimplification to characterize our health care problems one of public vs private delivery. Inviting competition will not fix anything. More novel approaches are required. While competition may be useful, it is not the only means of controlling costs. Corporations, especially publically traded ones, do not have a stellar history of balancing the public interest to those of their shareholders. Perhaps a co-operative approach, like mutualized insurance, where the customer is the owner,  might work in some cases. The real problem is one of vested interests, doctors, nurses, administers, bureaucrats, resistant to change, when a  dynamic framework  for change is what is needed most. If private healthcare cannot be stopped, those in it, must be isolated, highly regulated, separated, and taxed, all to support the public system.
