Unjustified discrimination artificially restricts the pool of labor for a firm. So there is no need for discrimination laws to protect workers from unfair treatment as free markets will do that automatically. Discrimination laws put a political component to labor relations. Qualifications are tortured to get a mix of people in a police or fire department. I was for that, as I did not want our cities to be policed as plantations. But then I found that black New York State troopers said there was no evidence against OJ Simpson in the Brown/Goldman murders in 1994. I am for fair treatment of all. But I am against all Non-Discrimination laws, as their cost greatly exceeds their benefits in my opinion.
