Max Borders‘ latest Ideas Matter update features a video debate on the role of labor unions and free markets in protecting workers’ interests:

Williams and Friedman have no trouble with the idea that markets create wealth and that government-enabled unions are essentially a labor cartel designed to exclude. The others seem to be trying to change the subject, to trot out the same old lines about unions as essential for “democracy,” or the necessity of unions in taming the robber barons. (Interesting also how willing Ernest Green was to pull the slavery card. But I digress.)

Although Friedman and Williams have no problem with any form of voluntary association, they reminds the audience that most unions use legislation as leverage (government power), which they find objectionable.
