If you paid attention, you would realize that women hate women who date men that are much older than them. The young ones are jealous because her man can afford to give her a higher lifestyle while their boys can't, making their boys look inferior. The old ones are jealous because they think they deserve that older man, not some upstart who hasn't paid her dues.
Men give it a high five.
The other way around is a different dynamic. Older women who have boy toys tend to be dominate over them. This turns the traditional dynamic upside down.
The only opinions that matter are of the two people involved with each other. Everyone else should butt out.
