I agree with you. To me, the rising population of escorts is due to a couple of factors:
Fewer barriers to entry than before (essentially, a payment card and internet access vs placing want ads) Easier access to clients (see above) Easier access to escorts (again, see above) Lack of decent-paying jobs for people starting a career and/or people who have been displaced via layoffs
Not everyone agrees with you, however, as evidenced in this thread.
