A large part of what got me out of my depression was making meaning for my life. Discovering what really matters to me, and living my life by my discovered values.
I'm also, now, easily the most optimistic person in my peer-group (I definitely was not before). I believe the world is getting better every year, and that the human race will rise to overcome all the challenges presented to us.
That's a myth unfortunately:
> Now, for the first time, researchers went beyond deaths to examine the global causes of illness and disability. They found that the single largest cause of disability worldwide was mental disorders – largely, the common illnesses of depression and anxiety. They caused a seventh of all the disability in the world. In the poorest countries as well as the richest, and at every socioeconomic level in between, mental disorders were the greatest thief of productive life.

That we've evolved for the former situation and seem to be miserable in the latter seems to be the grandparent's point.
If the odds of achieving your goals and leading a satisfying life in the real world approach 0% (e.g. because of hyper-capitalism and monopolistic, anti-competitive, centralizing market forces), then it's completely understandable that you'd want to escape into virtual worlds which give you the dopamine rush which your real life continuously fails to deliver.
It's like in The Matrix, it's not until you unplug yourself that you realize that the world is worse than it has ever been. Opportunities essentually don't exist at all.
Also the argument that "if they don't realize it, then it won't hurt them" doesn't apply because it will hurt them badly in the end. Once they reach a certain age and realize that they're wasted their entire lives on video games, star wars, star treck, lord of the rings, game of thrones, etc... It will hurt badly and they won't have any way to recover.
