There are two simple answers to this not very difficult problem:
- You ask them what they do for a living. Perfectly normal question, hardly likely to offend.
- You see the women with no clothes on? They are the prostitutes. Other women don't get their kit off in public to fool around in public with fat 60 year old politicians. Believe me. They really don't. You have to pay them. It's called Price Equilibrium.
Obviously not much of an economist.
