Right now insurance companies are dictating whether or not you are covered, and how much, if you have existing conditions, the cost of your premium, which doctors are preferred providers, etc.
Apparently GGK just wants to replace the evil insurance companies with a Big Brother who makes similar decisions - contingent care, unequal benefits based on your weight or lifestyle choices, etc. You would think "single-payer" and "universal" health care would be pretty clear terms, but I guess if you smoke crack and worship Satan, well, such concepts are out of grasp.
