People born Into poverty can escape it with hard work without needing prostitution. Hundreds of thousands of people have done it. Men and women do it all the time. And Montreal has a particularly cheap education system in place. I would say it's a Disservice to suggest to a young women she needs to be an SP in order to succeed, or that being one is some great and highly intelligent choice to get ahead of the curb.
People having debt to pay off is either due to poor decision making or school.
School debt is common. People pay it off all the time.
Single parent? So what? Just as good as two parents a lot of the time.
Broken family? Ok. They get some leeway and sympathy, but I've yet to meet a single escort from a broken family...that's a drug addict, or pimped.
Ok, let me turn this around. How about this: only unfortunate dumb dudes with no social skills and charisma, looking just a little bit better than apes and having no other good qualities except of some additional money which they often did not earn but just steal are buying sex services from prostitutes. Instead of trying to have a real girlfriend or even mistress and working hard to earn respect and love from a woman they choose the easy way of buying a surrogate. Looks harsh, noy true and probably too general? Yet you choose the very same tone and generalities to characterize SPs. Life is much more complicated than this. Though probably only people who went through real life challenges and misfortunes and were not gliding from birth on a smooth ice can understand this.
