Do people actually care if a rich, beautiful girl dates a poor guy? Do people actually care if a 10/10 woman dates an “ugly” guy? People will see couples like that and say, “He’s out of her league.” Do people actually care about this? If Jessica Chastain, Angelina Jolie, or Alexandra Daddario dated a 25-year-old man (or woman) who works at a grocery store while attending college, would people actually care, judge, and look down on it? (Real people, not just keyboard people.)
A lot of people do as a way to judge a person’s rank in society. The attractiveness of a person’s spouse is a common metric for how successful someone is. So, if a highly attractive woman is slumming it with a man who appears to be well below her status, it is confusing for a lot of people.
