Sure, once they pay their tax for decades, pay their premiums and copay, and buy their supplimental private insurance (not to mention facilities diffusing some costs through higher price setting of private parties). It's not a bad system, but you can't really scale a system that takes decades to fund and requires all these other costs. Especially since this conversation is about debt to medical facilities which can still occur under Medicare (or be forced onto Medicaid). Yes, supposedly it would save the US $2 trillion over 10 years, although there is some debate on that.
