Good one!
I dont think there is such a thing as anyone being over-educated. No one can have too much knowledge.
As a law student, from seeing the frum women in my school, I can say very simply that there just is no time. No time for dating, no time for a wedding, sheva brachos, pregnancy, childbirth, ect. ect. ect.
To be successful, many law students work 12-18 hours a day, get internships and jobs during vacation, and are just plain exhausted whenever they aren’t studying. Good starting associate jobs are hours heavy and require a lot of commitment. There is only so much any one person can do or worry about.
