I'm glad you've had a better experience with the NHS than I have; my wife has a chronic condition and has had a pretty bad time in the NHS - she hates going to the doctors now from how many times she's been called a liar or accused of just trying to feed a painkiller addiction (despite not actually asking for painkillers). All because many doctors seemingly struggle to admit that they don't know what's wrong.
I just bring this up because I think (and I could be wrong) that some people see socialised healthcare as a panacea but my experience with it is that it's actually very inconsistent and regularly lets people down (not just my wife, a good few others that I know as well). I still wouldn't choose the US system over the NHS though, not by a long shot.
