Wake up and smell the coffee. There ALL desperate/troubled/damaged/have "issues". Some are better are hiding it than others.
No "normal" wumen I've ever met would do the things these hoors are doing for £5K a day, never mind a few 100 quid.
How many "normal" women you know have you actually asked? And if this is your honest belief, why are you still punting, Randy? I'd already gathered you're a rather unscrupulous character, but expected even you to have a few more principles than that.
More to the point, while I'd agree the vast majority of women in the world would never consider prostitution as means to make money, if that's who you want to consider "normal", the remainder who do work as escorts aren't all vulnerable as you assert.
Obviously many are troubled, desperate, coerced, or even trafficked - i.e most Romanians, effectively locked up in brothel flats who any half-decent punter should avoid, as well any others with such warning signs. However, as for the large amount of other girls, while they may not have what a relatively conservative society considers a "regular" attitude towards sex, men and relationships etc. (they also need an incredible degree of courage as well) it certainly doesn't mean they're "damaged" in some way and I'd say this is what you're confusing.
Some plastic barbie-doll types and even more natural students working in Mayfair and Kensington will be laughing all the way to the bank, such as the "sugar daddy" stories in the news this week. Most other prostitutes working off Adultwork however, will simply be making a tidy few quid in a short space of time in no other way they could.
Yes, some girls are exploited, some do have a troubled past, and these should be avoided at all costs, even reported to the law in my opinion if some scumbag is mistreating them as I've highlighted before. But just because they ironically have the balls to do a job that nobody on here would, and fairly reap the rewards for it, it doesn't mean all prostitutes are damaged or somehow disadvantaged and vulnerable in that regard. Most are far more "normal" than you think. I was going to encourage you not to be so black and white, which I know would be difficult, but there's not even any white here, only black.
