You're closer to the truth than your mods would admit.
Contemporary crusades against minimum wage by economic libertarians are often shouted down as racist, but when minimum wage laws were enacted, they were obviously racist against blacks. You see, before minimum wage laws, blacks commanded lower wages, largely because Americans at the time were racist fucks. In old silent movies you can see signs in the background that say 'colored waiters wanted'. Guess what, they didn't want 'colored' waiters because they liked black people, they wanted them because they would work for less than white people (due to less competition for their services).
This resulted in a predictable tizzy of 'deytukarjabs' by the empowered white majority, who instituted minimum wage. With minimum wage, if you have to pay X dollars per hour anyway, you hire a white person for X dollars per hour. The practical effect: no black people get any jobs until every white person who wants a job has one. This is all politically 'sold', of course, as an empathetic measure which will benefit the disadvantaged.
