"Huge savings??"
From WHAT? What's going to cost less? Where is the spending going to decrease? Where is demand going to drop? What "savings" will balance a new Federal outflow of a quarter trillion a year by 2019? As for benefits to employers and others, have you forgotten who's going to be coughing up that quarter trillion?
If there is some trick for creating huge savings in a government-paid program, then why is Medicare going into the crapper?
