I don't know what percentage it is, but some men who aren't entitled dicks are still emotionally immature. Not in the way of being spoiled, but in the way that most boys are emotionally abused as children, forbidden from (or humiliated for) showing any emotion other than anger. I liken it to "emotional circumcision," cutting off a really important part of their self, that leaves them disbaled for the rest of their lives. Unless, of course, they get therapy.
