While I consider myself a proponent of the free market, I think my work as a programmer blinds me to how much rent seeking underlies other high earning professions in the US. Doctors, lawyers, financiers, accountants don't really operate in a free market, rather they work in a system that is better understood as defined by laws. The reason all these fields (with exceptions for parts of medicine) are so lucrative, is because they have thrived in a system mandated or failing to be regulated by law. It is naive to think that said groups do not wish to sustain and propagate that privilege. Market adaption is an important force, but one that for all practical purposes exists within a framework society has created. I am expecting Americans to slowly get to terms with this reality as the economy recovers after long period of credit expansion and it dawns on more people that it has always mostly been a zero sum game.
EDIT: grammar
