It's certainly happening in Sweden, but it's far from common. An almost universal constant in research of this nature is that women highly value a partner who earns similarly or more than them.

Sure does, you just don't marry if you don't find anyone you want to marry. It is that simple.

For example, we can see that even in Sweden women who earn less are more likely to marry and men who earn more are more likely to marry. Women who earn a lot are less likely to find a partner they like as you say.

It's the same in germany. It also comes down that people here don't care that much about degrees but value other things more if they have to choose.
