Honestly, like maybe I'm a bad person for that, but I find this kind of disgusting.

The problem raised by op is not a trivial fact but something that happens a little too often imo.

Honestly the major problems with this kind of relationship tend to be subtle social dynamics and patterns that aren't really apparent until you've seen it a few times. And when you've seen it a few times, you notice that the older partner tends to have some of the same toxic beliefs and behaviors over and over again (very frequently just old-fashioned sexism, but quietly), and the younger partner is often the "go along" type who doesn't see that they don't have to put up with that.
