Emanuel: Although 'not a perfect law,' ACA is protecting patients

In his new book, "Reinventing American Health Care," Ezekiel Emanuel offers some surprising predictions about where health care is going in the next decade and beyond, including forecasting the end of health insurance companies as we know them. Along the way, readers will learn more about what's actually in the Affordable Care Act and its tortuous political path to passage. There's health care trivia too, including the fact that compulsory health insurance dates back to 1790, when ship owners had to buy medical insurance for their seamen. Who knew? Emanuel was a special adviser on health policy to the While House from 2009 to 2011.
