How could socialist Berkeley legalize prostitution as it would encourage free enterprise and profit? It would be more in keeping with Berkeley to to make it legal to give away sex or have it provided for the common good by the government, but make it totally illegal to profit from it. I suppose they could justify the action if the workers (i.e. the prostitutes) totally controlled the means of production (sex), but outlawed pimping as that would be worker exploitation by capitalists seeking to make profits from the labor of others.
A pimp is not an employer. He's more of a slave owner. The women give him ALL the money.
In return, he gives them clothes, a place to stay, promotion, and legal/medical coverage until he decides otherwise (or another pimp takes one of his women). He will track down a girl who leaves his pool.
