That's interesting to consider but it may stem more from your culture there and first-world country morality(?)
Doubt it. Women are always reduced historically to their sexual value whether it is recreational or reproductive.
I point of fact, I would argue the opposite direction in that the first world by definition is more K (slow life history strategy) and 3rd world of necessity more R (fast life history strategy). The R strategy environment is more apt to promote lots of sexual partners and by extension women being more sexually available for short term couplings.
The 1st world countries becoming more amoral, experiencing a severe collapse of faith and an upcoming social collapse has us moving towards R strategy behaviors. We can all provide an unpleasantly long list of the live fast die young indulgent selfish and hedonistic behavioral shifts in Europe and the European diaspora nations in the last 80+/- years.
