This sounds like the first speech I received in boot camp from. The Drill Sargent was more succinct, "your momma may love you and think you are wonderful but we don't". I liked his speech, I do not know what effect it had other than some entertaining shock value. No matter what he or anyone says at a commencement the world is going to make adults out of most of these people. Life happens and growing from it follows, hopefully.
It seems that every generation is viewed as soft by the previous generations. Maybe that is the way it is supposed to because the previous generation is supposed to prepare the next for life; as Ronald Reagan said, "Each generation goes further than the generation preceding it because it stands on the shoulders of that generation".
