Which is more likely to get a client--the one whose calls usually go to voicemail, or the group that has a dedicated phone-answerer/dispatcher? If you're engaged in any high $/hr occupation you're better off hiring out scheduling than doing it yourself. Why should prostitutes be any different? But one prostitute doesn't need one scheduler so it's cheaper to work as a group. What's surprising about people using the most advantageous business model??
Oh, I understand the economies of scale in working as a group. I don’t see the value of having a pump/master/owner/enforcer. That is if prostitution were as safe as you seem to claim. But it’s not. If it were, there would be no need for the kind of security/guards that are required.
And where did I say anything about pimp/master/owner/enforcer??? That's purely you trying to impose your faith on what I did say. You are making assumptions about the power flow that AFIAK none of actually knows.
No, you seem to believe that the only way a prostitute can earn a good living is to have someone to manage their appointments, and handle all the pesky business details. I’m certain some prefer that kind of set up. But certainly not all refer to work in that kind of set up.
It’s almost as though you believe women ( since you seem to feel prostitutes are at least female even if some cannot necessarily be considered adult women) cannot be in charge of their sex lives. Is the business set up to keep the customers in line? Or the prostitutes?
