In school i've seen a lot of stubborn idiots, who were successfull because they got on the teachers nerves until the teacher gave them good grades. or people who were just conformists and got good grades because they were more or less invisible.
it depends on what the goals are - if you want a society of conformists, dominated by loud idiots, that's the way to go.
