Of the 11 WGs I have been with, 3 clearly had other professions: artist, fitness instructor, and just-qualified legal degree. I'm sure those three (or nearly 30%, and I don't know about the others) had options but also seemed to like escorting, when they could be making money in other, less stigmatised ways. If you do AW searches using words like educated, it is interesting how many women this pulls up. Some may be exaggerating, but some clearly aren't.
