> While the article seems to criticize rent-seeking behavior only in businesses and professions that require lower levels of education, if we combine this article's statements with the often repeated claim that the US pays roughly twice as much for health care per capita as other developed countries it seems reasonable to ask: Is there a rent seeking problem in the medical and dental fields too?

Wait, are you suggesting that the regulatory barriers to private competition in medicine and dentistry are higher in the US than other developed countries?
