You keep trotting out this argument that boils down to "I've lived under a nationalized health care system, you haven't. Trust me, it sucks." And for all I know, when you last lived in the UK, maybe it did suck. But as an American who's been living in the UK for the last six years, I can tell you my experience with the NHS has been almost completely positive. The doctors are professional, the facilities are clean, and I always can get help immediately. Two times I've had to dash out the door the moment after arranging an appointment to get there on time. The level of care for me has been indisputably superior to what I had in the US, even with good insurance.
