Who decides when to stop Medicare/Medicaid payments? The government has mandated that hospitals must treat illegal aliens who show up in the ERs along with the indigent. The government pays for may things that are wasteful. Again, who decides what the government will or will not pay for?
Medicare, Medicaid and Obamacare combined with a huge and growing glut of old people combined with new, enormously expensive equipment and procedures which make it possible to unreasonably and unnecessarily prolong the lives of people who have become permanently unproductive will cause the present system to collapse.
Just how much do you think that taxpayers (people who are productive) can pay?
The inevitable death of the current system is as certain as your death.
