"It's not just women, both men and women are unlikely to date and marry across those lines. It just doesn't matter for the men because the pool of educated women is so vast that their own classism doesn't really punish them. But being unwilling to consider working-class guys affects women in ways that it doesn't affect men. It's totally unfair, and I get that, but it's not like only the women are choosy and the men are all open-minded."
That's what assortative mating is all about:

Girls choosing to do so because that's how they prefer to see themselves and the image they like to project is not, or at least, the idea that it is would likely be controversial among self-described feminists.
Firstly we more women in college.
Secondly guys are less likely to judge their mates by whether they do attend college, so you end up with a dynamic where college educated men are dating both 'up' and 'down' whereas college educated girls only want to date 'up'.
This mentality of dating 'up' based on societies ideals of what 'up' is somehow feels like hypocrisy as many of these girls are staunch feminists.
Why are these non college educated guys not good enough? Are they bad people because they didn't go to college?
Oh well, as a college educated guy, im not complaining.
