That’s not very fair though, unless this in the context of some “women were better back then!” kind of simplification :)

I think modern men have an ahistorical view of female beauty, so the concept of universal marriage sounds more appealing than it was. We can't go back to that era, and I doubt anyone born today would actually be willing to do so, if they saw what life back then was actually like.
People have an ahistorical view about everything, basically. The concept of marriage generations ago on anyone’s head is just a soup of decontextualised biases.
I've also noticed that men tend to heavily discount womens' age in old pictures. They see pictures of 16 year-old factory girls from 1910 and get all excited because they think she's 25.
