I wonder if a big reason for depression, especially among males, is that there are no problems any more. "Developed" modern society has basically solved all issues of "survive, have a roof over your head, have food at easy access, , dont die from a tiny cut, get sex whenever".

Tribes a thousand years ago would have killed for that sort of comfort and not having to fight every second to live. Now its "solved" (obviously I'm leaving out unhoused people and third world countries here).

We want to solve problems. We want to invent. But theres nothing left to invent. People feel worthless, and either get depressed or turn into gigachads.

Just a theory.
