I don't mean to come across as snarky, but there is a lot to unpack in this statement. First, you inherit something that your parents or guardians own, and the world is definitely not owned by them. Second, why feel powerless if they are actually going to inherit something? They can always fix it after they take control. Again, I am not being mean, but just showing how you can think of this from a different angle.
Now let's circle back to the issue of social media. Kids who are tuned in to social media are going to constantly hear exaggerated claims of gloom and doom, and that would numb their senses. This prevents them from focusing on the present and all the things that you build for yourself are in the present.
The point is -- no matter how you frame it, the information overload is taking its toll on everybody who is exposed, not just teens.
