I think you touch upon something sound, there - while societal and group trauma is certainly a thing, we generally call it culture.

On the individual level… for me, certainly, the hardest part of dealing with my particular flavour of living nightmare was that literally nobody could relate to it, and the others who went through it are scattered to the winds. When you explain something painful and the response is “I would have considered myself lucky to be in your situation” or words to the effect, it’s a rather lonely thing.

In the past, if you said “the baron came and murdered my child on a whim”, people would likely sympathise - in today’s society… well. We have such a buffet of lives and possibilities that comprehension of the worlds of others is increasingly challenging.

Solzhenitsyn put it well - can a man who is freezing understand one who is starving?
