Prevailing Wage Laws: Public Interest Or Special Interest Legislation?(Report‪)‬

People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices. But though the law cannot hinder people of the same trade from sometimes assembling together, it ought to do nothing to facilitate such assemblies, much less to render them necessary. --Adam Smith (1776)
