In the West also, rich men have access to younger women as well. I used to work in a government building run by the military in one of the Western countries ( I don't want to mention it, so I don't get court marshaled). This guy who was a general was married to a woman who was 15 years younger than him. He was sent to overseas deployment. She was working as a civilian in the building and was courting me while her husband was out. I was much younger and single at the time and she was hottie blonde.
Moral of the story, men with money and prestige, irrespective of where they're, always had this desire of being with hottie, younger women. You just can't change that fact.
There are also middle-aged and older women who prey on younger men. In the West, they are known as "cougars".
