To make matters worse, people almost never talk about how this state of affairs makes them feel.

Part of this is simply because they have no idea what life was like until relatively recently in human history.   They’re unaware of how in the village-scale times that comprise the bulk of human existence, most of the people around them would have known them at least to some degree, and whatever useful abilities or positive attributes of character they had would have been recognized and valued.

Also, our transformation into a hyper-scaled world has been going on for quite some time.  It had already reached levels troubling enough to make it a force behind the rise of fascism a hundred years ago, in the run-up to World War II.  Since hardly anyone's noticed a change within their own lifetime, we're all a bit like the frog that never jumps out of a pot of water that's heated gradually to a boil.

Another reason for people’s reticence is concern that speaking about how small and inconsequential they feel might result in other folks dismissing them as just whiny losers.   The same fear can make us similarly dismissive of ourselves—a further stressor that could make our lives feel outright unbearable.   As a result, we tend to resist acknowledging these feelings even within our own private thoughts.
