I know we all hate people like Bezos and Gates, but the real leeches on society are the people who directly own capital responsible for natural resource exploitation.
While tech billionaires are bad, the capital that they own is all tied to R&D or software, the resource barons on the other hand, own and control vast swathes of land and infrastructure that exploit natural resources.
Oil barons, real estate tycoons, Coal barons are the greatest evils.
Know your enemy comrades.
I would say that the tech giants are a more important enemy. Very hard to get people to unite against natural resource barons when they are systematically brainwashed by data collection and propaganda pumped into their social media 20 times a day
