Is the US Ready for Universal Coverage?

America's shortage of doctors has been growing for years, and the Patient Protection and Affordable Care Act is going to make it much worse. Even supporters of "Obamacare" agree that, with 30 million new patients in 2014, there will be 62,000 fewer doctors than needed. That's just two years away, but it takes ten years to train a doctor, so there's a crisis just around the corner. Nurse practitioners and clinics in pharmacies can take up some of the slack, but can they really replace MD's? Will the gap in quality care between wealthy Americans and the poor grow bigger than ever?
