No doubt most Mamas send their boy off to college hoping that he can grow up, straighten up and man up. Sadly, too many of them bring their problems with them and get fed a lot more when they get in school. It's that way everywhere.
Kids grow up in a culture of emotion and entitlement with very little understanding of personal responsibility; some are the product of dysfunctional families which could not, or didn't know how to raise them with a moral and civic ethical code of acceptable behavior, and schools which do not demand that kids learn the sciences and the rule of law. SOME, that is, not ALL.
The ones that Mama and Daddy raised right and insisted that they behave, they're here too. They are the ones doing it right.
