Interesting article, but it doesn’t mention modern day propaganda and misinformation being disseminated on mainstream and social media. Status quo elites are doing more than just backing Donald Trump and Boris Johnson.
Every human conflict throughout history has been a class conflict.
My immediate thought is that that’s not true, and that tribal disputes over territory aren’t necessarily class-based. I guess perhaps you could frame it as: the class structure in the aggressor is what prompted the dispute, despite the defender being an egalitarian society?
Depending on your definition of “tribal disputes”, these occurred in a time where property was not yet ceased in any way and it’s what we would call primitive communism, so since a class based society did not exist we couldn’t say there was class struggle, I guess. Still, after that point every struggle between humans has been a class struggle.
