The whole system is warped! and that’s why there’s a Shidduch crisis. The boys have created for themselves an elitist attitude and it’s not a healthy attitude.
You’ve got it backwards. There’s a shidduch crises because there are more girls looking to get married than boys looking to get married. And yes, some boys therefore develop an elitist attitude; it means they don’t have proper midos to begin with. Some girls, despite the situation, still have an elitist attitude. Those girls also don’t have proper midos.
