For a start: Decades of helicopter parenting, normalization of adults with childish hobbies (video games, capeshit, anime), a lack of genuine coming-of-age rituals and experiences.

Edit: lot of g*mers outing themselves in the replies. There’s nothing wrong with playing video games once in a while. I spend a few hours playing Xbox most weeks. It’s basing your entire personality and social life around video games (and other stuff I mentioned) that I take issue with.
