It's a New Gender Gap: more and more it's girls who populate educational institutions. As the linked article says, "Girls are better able to deliver in terms of what modern society requires of people -- paying attention, abiding by rules, being verbally competent, and dealing with interpersonal relationships in offices." To put it another way, men make things work, women make nice within a system someone else has set up. If the world is mostly organized and administered top-down, girls will do better, at least among the general run of drudges, and men will get disgusted and bored, and drop out or act up. A few of them will make it big, most won't, and the women will complain about the "glass ceiling" and wonder why they can't find reliable men.
