I think it's kind of funny all the responses you your legitimate question are essentially people presenting their political opinions. There is a factual answer to your question though. In the early 1900's people tried to argue exactly that that unions were an illegal conspiracy under the Sherman Antitrust Act. This interpretation was against popular opinion at the time and in 1914 under the Clayton Antitrust Act the legality of organized labor was clarified making it specially legal. The short answer to your question as to why Unions are ok but collusion between companies is not is because there is an exception in the Antitrust laws. http://en.wikipedia.org/wiki/United_States_labor_law#Workplace_participation http://en.wikipedia.org/wiki/United_States_labor_law#Workpla...
