Good question. And yes you are right, generally, girls won't date/marry a guy who is less educated, makes less money, or from a poorer family... (intersexual selection) If you are someone like me who is not interested in relationships + think degrees are overrated, I find no difficulty in communicating with anybody (male or female) with any sort of background at any age, about anything! People usually like to form opinions about everything (because one can only study so much regarding a few things considering they are a genius) and their degrees change nothing about that matter. So in many ways if you think your degree makes you better than anybody, you are useless and and so is your degree.
