What model should the US use to provide universal healthcare?

4. I prefer a private system with Insurance companies and hospitals forced to live up

to promises that they make. The ACA is a good start, with safety nets for people that can't afford health care insurance. I want to see the government provide free medical school training to med students that are going into general practice, with the condition that those newly minted GPs serve in clinics that provide care to low income and lower middle income communities. I want to see regional exchanges where like minded states can group to provide low cost insurance and health care to their citizens, New England, the upper and middle-Atlantic and the West Coast states would likely flourish in such a system.
