Not necessarily, the brothel is nothing more than a "legal pimp", or employer if you will. Like any good business model, the object is to maximize profits.
IMO, taking care of your employee's is a high priority and can add substantially to the overall succes of an operation in regard to meeting the objective.
However, my view isn't shared by all in the business world. So just because you provide a legal working environment, doesn't mean you are looking after the best interest, or safety, of your employee's.
