If you want to understand the basic philosophies that keep inequality and discriminatory hierarchies embedded and supported in societies through the use of justifying mythologies and repressive, often violent policies, even in societies that are ostensibly or lean towards democracy, this video from the guy at Innuendo Studios simply and straightforwardly encapsulates them.
It’s important to note that capitalism is largely an economic system, not a political one, and that it is possible to do forms of capitalism that are more equalitarian, including through regulation and consumer protection (the latter tending to keep more people alive to be able to participate in both democracy and capitalism.) As the video notes, it’s not a battle between the two specifically. It’s about how people regard the nature of human beings and violence, which comes from what they are taught in their culture and sub-cultures.
And this coda video of his I think I have to add here:
