That's because it's already there, jgd. National health expenditures are projected to hit $3.35 trillion this year or $10,345 for every man, woman and child. 

We are more expensive because insurance companies rack up huge profits. Drug companies do the same, by obscene charges - sometimes increasing prices 5 times when their cost of production hasn't gone up. Surgeons and hospital based specialists like anesthesiologists and radiologists have massive charges and non-profit administrators have huge salaries. These are all private business decisions which the government has done little to curb.
Fact is that during Obama’s presidency, the rate of increase slowed and the uninsured rate went down nearly by half, even though Republican governors declined to cover millions of their state residents through expanded Medicaid. So now fewer and fewer people can afford healthcare, and serious government reforms such as negotiated Medicare drug costs and the public option are not offered.
