“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. It is impossible indeed to prevent such meetings, by any law which either could be executed, or would be consistent with liberty and justice. 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, Wealth of Nations
亚当•斯密(Adam Smith)在《国富论》(Wealth of Nations)中写道:“同业中人,会在一起,即令以娱乐消遣为目的,言谈之下,恐亦不免是对付公众的阴谋,是抬高价格的策划。想用某项能实施却又不违反自由正义的法律,来阻止同业者不时的聚会,固属难能,但立法使其便于集会,尤其是立法使其集会成为必要,却亦是错误的措施。”(郭大力、王亚南译本——译者注)
