Yes. Loneliness is one of the most consequential and enduring trends in the history of the West's development, but it is hardly studied (despite Putnam). I think, in part, because the development of the trend has been really slow.

We have no idea of "the amount of community" that our ancestors had, and so it's difficult to compare or even realize that there has been a change.

I don't know Russia well enough to be able to comment on it.

Yes, I agree, but some ideologies lead to authoritarianism, others do not. Wokeness, for example, was inherently authoritarian, which, following Jung's logic, is probably why they're obsessed with Hitler.

I would disagree. Social Darwinism and the eugenics practices that stemmed from it were more a consequence of the belief in a group-based conceptualization of society than free-market capitalism, which is inherently individualistic. In fact, eugenics were widely spread in Scandinavia well after the end of WWII.

I also disagree on Hitler's appeal to providence. He had built this whole program where young women had been chosen to reproduce with tall and handsome German men to make the "people" stronger. While I understand the authoritarian character of Stalinist Russia, I struggle to understand that of Hitler. I have yet to read someone complaining about the lack of freedom in Germany in those times. In fact, people seemed to be very happy on the movies I've seen (Triumph of the Will, for example).

But tbh, and rather surprisingly, despite the fact that Hitler is present 24/7 in the media discourse, I don't know much about him nor about National Socialism. I think that is because most of the developped world was in fact very pro-Hitler before the war, and this is something the current leaders would rather us to forget.
