Benefits
A single, childless, male individual in good health such as myself generally has the privilege of not really thinking much about health care except as a very abstract political/policy issue. Then comes the day when you come to speak to the benefits manager at your new job and you realize . . . America's health care system is really terrible! The sheer quantity of forms and things to consider is mind-boggling, to say nothing of the sob story of rising premiums now being passed on to new employees in the form of the 90/80 PPO plan switching soon to a 90/70 plan, etc., etc., etc., etc.
The sheer reduction in the level of mental energy -- to say nothing of actual time, economic resources, colores pieces of paper, etc. -- expended on this kind of thing seems like a good enough reason to move to a simple national health insurance scheme.
