The loss of profit in the industry because of Medicare is offset by increasing the cost of medical procedures that is burdened by those outside of the Medicare system.  This is a half-baked health system hybrid that is seriously flawed, and NO socialized plan should be passed without the costs and payments understood.  

Also, any socialized system is going to serious compromise in service balanced against cost.  Don't expect to get that MRI for nothing at the drop of a hat.  With Americans having some of the worst health habits, expect to pay to support those.
