Healthcare in the U.K. is basically a monopsony. It is also, like many traditional high-paying industries, one which requires a bunch of education and a period of not particularly good conditions before getting good pay (but still having long hours.) Certainly in the U.K. one must suffer as a junior doctor for a while before more lucrative positions become available. While I would like people working in healthcare to be better paid and I’m sure the U.K. system could be made better, it is easy to feel that not having doctors paid like Americans keeps costs down a bit (though maybe that feeling is not bourne out by facts.)
