Earlier quoted context omitted.
Yes, in places where there is an extreme power imbalance, with few employment opportunities for the disadvantaged, and no morals or accountability among elites, all manner of scummy things happen. We should strive to ameliorate the conditions in the world that make this happen, so that young women can aspire to being scientists or doctors or businesswomen, instead of some corrupt asshole’s decorative servants.
It's this type of attitude that makes most on the right cringe at the left. The notion that if someone isn't living their life in a way that you deem to be of value, then there must be a "power imbalance" that needs to be corrected. Has it occurred to you that not everyone wants to be a doctor, or "businesswoman". And that many young women actually like sex and furthermore like using their sexuality to get things in…
The problem is that many people in many places are stuck with a choice of either working themselves to death at a job they hate for shit pay and no benefits (or maybe just starving on the street) or else selling themselves to a very wealthy asshole. When that happens, it indicates a profound structural failing of the society. Prostitution or feudal servitude shouldn’t be anyone’s only shot at a comfortable life.
In theory there’s nothing wrong with a career in private security. But it’s messed up to be an enforcer for the dictator family who who rule Equatorial Guinea and live lavishly while keeping the rest of the country in miserable squalor.
In theory there’s nothing wrong with being an actress. But it’s messed up if getting a leading part depends on giving blowjobs to the studio executives.
Etc.
> It does not imply a "power imbalance".
If the young women in such relationships had all the money and power and the old men had none, how many of those couples would still be sleeping together?
