We are so divided and mislead that I feel confident there is a significant sum of non-ruling class individuals who are completely for their own oppression for no reason other than spiting a perceived “other”.
Some other specific examples that don’t all flow together:
Globalism promised efficiency and a way to materially improve conditions for people as consumers and producers. However it has been used as a cudgel to threaten workers that would ask for more and keep down workers who have no other option. Also pitting working class people against each other for the benefit of a few.
Social media, it promised untold communication between people who would never have been able to communicate before, and it would allow them to spread ideas. Instead it is used as a dumping ground of nonsense information, drowning out any semblance of coherent thought.
