Perhaps this is just due to the fact that I've never had a friend, but I'm not sure what the difference is between what the professor is describing and say a sex worker or escort. So long as the client can afford to, all of those criteria are fulfilled.
Is there something I'm missing?
Yes, but it's difficult to describe in words.
Part of it is the reassurance of knowing that there's someone you can depend on when times get tough. An escort wouldn't help you back onto your feet if you lost everything; they'd just move onto the next client.
The "talk" you get from a paid relationship is different too. For starters, they're not going to risk losing your business by telling you a difficult truth that you need to hear. This could cause you to become offended, after all, and isn't their place to tell you.
Dogs are pack animals, just as humans are, and part of the reason we like them, is because they have and bond via traits we... wait for it... like!
And while dogs have a very specific place in our society, that does not mean human friendships, built upon the same ideals and core fundamentals, are the same.
But you knew that, I presume?
I love my dog as much as I love you
But you may fade, my dog will always come through
Bribing and rape? Explain?
Also in fact it is often not even a bribe, in cases of sex slavery and human trafficking. The john is paying someone else to organize the rape for him.
I find it hard to believe these women have no other options than to sell their body.
