Chaverim, the other girls don’t have that perception because they marry kollel boys.
OK that was a little snarky 🙂
Usually, there is a reason for a subset of people to have a certain perception. Could it be their prejudice? Maybe, but generally people attend seminaries that are hashkafically on a similiar page as themselves. So, marrying a man who learns (full time or not) would be extremely important to them anyway. So, by the teachers preaching a little harder for kollel, they may be getting the perception that thats the only way to go and anything else is a failure.
I’m not placing the blame solely on seminaries – its just what I’ve seen/heard from conversations.
