Granted our healthcare system is very inefficient, objective data indicate that among developed countries we have the most expensive and one of the poorest records on healthcare. See Time Magazine Article:
The U.S. health care system has been subject to heated debate over the past decade, but one thing that has remained consistent is the level of performance, which has been ranked as the worst among industrialized nations for the fifth time, according to the 2014 Commonwealth Fund survey 2014. The U.K. ranked best with Switzerland following a close second.
Much can be done to improve the efficiency of our healthcare system and to improve the Affordable Care Act, ACA. However nothing I have read or heard in the past few days convinces me that the Republican approach will do anything to improve and in fact will cause serious damage to our healthcare system.
