Yes, age doesn't really matter when it comes to power imbalances, hell younger people can have power over older people in relationships, it's not as common, but it happens. Each relationship is different, it's not black and white that's for sure. I don't agree with this really though..
..I definitely don't think
most younger women or men, in a relationship with a significantly older person, have power over their partner. It depends on the circumstances of their relationship, but I generally believe that most older people hold a monetary and/or career advantage over a younger partner. And I feel like in the majority of these relationships, the older person knows they can always find another young attractive person if their partner suddenly left them, therefore the younger person is the one with pretty much everything to lose. (Granted young attractive people can always find someone else too, but it's not as easy to find a single well-off person, when compared to a well-off person finding a young attractive partner)
In the cases where the older person isn't rich, and isn't some big shot doctor, actor, musician, etc... then the power imbalance either doesn't exist, or the younger person can actually hold the advantage, since they have not nearly as much to lose. The older one would be much more willing to do whatever to get their young attractive partner to stick with them. Though in general these relationships where the significantly older one
isn't rich and/or has a top tier career, tend to be more founded in love anyways, in general those relationships come off as far less shallow in my opinion. It's not to say that
all relationships that have some kind of imbalance, aren't founded in love, because quite a lot of them definitely are.
Anyways, this is the last I'll say on this topic, I don't mind discussing these sorts of topics, but I don't wanna flood the thread too much with it.
