As a U.S. based software engineer, I can say that medicine is not the only sector that has over-priced professionals. I get paid a ridiculously high salary compared with my European counterparts. I've honestly always wanted to move to Europe, but the salaries here keep me from doing so. I don't understand how the U.S. gets away with it, to be honest. With a global economy, I don't understand how we manage to stay competitive. Same goes for Silicon Valley vs the rest of the U.S. I don't understand how there can be such a price differential, and yet the most pricey places seem to win economically.
