Bordering or average looks were good enough for an escort to make a living in some markets before but not anymore. Now, it's way more competitive.
As much as I agree with your post, I have a few things to add:
"Undereducated"? What does that mean when it comes to escorting?
Escorts and all migrants who come here from those countries appreciate the American dream, especially after making $15-$40 per trick. They live within their means, save money, etc. I know for a fact American born escorts of white trash background sooner or later overspend, do drugs, show no work ethic, don't save, run out of money, etc.
