The Deception behind Government Licensing Laws-Rothbard

“How much licensing requirements are designed to “protect” the health of the public, and how much to restrict competition, may be gauged from the fact that giving medical advice free without a license is rarely a legal offense. Only the sale of medical advice requires a license. Since someone may be injured as much, if not more, by free medical advice than by purchased advice, the major purpose of the regulation is clearly to restrict competition rather than to safeguard the public.”
