In western Europe:

A walk through an area popular with tourists one notices a number of street walking prostitutes...

Around them are "normal women" going about their day, to work, to their families etc.

What makes those first women prostitutes?

>In many cases they are wearing more conservative clothing than the normal women
>many of them have had less sexual partners and done less extreme sex acts than the normal women
>many of them refuse to have sex with HIV infected migrants and gangbangers
>they charge considerably less than the average divorce settlement, house payments, meals, holidays, dresses that the normal woman charges.
>they will sleep with you if you aren't a CEO 10k a day
>they are more likely to use condoms when having sex with strangers
>more likely to get STD tested
>more likely to be technically employed than most normal women since they're "working" right then.

I feel like neo in the matrix, finally seeing the source code. Like how has no one else realised this, everyone is just going about their day, oblivious to the obviousness of the reality around them.
