I have seen, over the ,last ten years, a great depression, as in mood. People are getting more depressed, and that leads them inward, and it is driven by anxiety. Most people are "flight" when they are faced with anxiety.
And the capitalism and online world has made isolation much easier and way more "enjoyable". Movies, porn, food, all of it acquired without a single human contact. Now people are clamoring they want to work from home as well, making loneliness even more available.
This is the outcome of hypercapitalism[1]. Extracting labor from the humans while feeding it all its' needs through the tubes of the internet.
I am writing this in a Starbucks right now. Ten years ago I would find couches and comfy chairs in every store. Now? stiff Uncomfortable chairs in a cold industrial setting, the store and counter set up for rushed to go orders.
This is not about something being wrong with people, it is a system that is tearing us apart.
