Just because patriarchy primarily benefits men, it doesn't mean it's all their fault. That said, it's important to note that they stand to gain the most, meaning to get to the source you must identify and address those men than support it directly and out in the open.

You could say the same for capitalism. It mostly benefits those with capital, but literally everyone still struggles under such an economic system due to it's core tenets of sacrificing personal well being and exploiting labor for maximizing profits.

Same goes for white supremacy. It mostly benefits white people, but it absolutely impacts them negatively, as well. Scholars will still tell you that white supremacy is defended and perpetuated by nonwhite people but the ones with the most power to defend and maintain systemic policies are typically going to be white (or funded by white people).

I don't know how you dismantle a system without addressing it directly and understanding who it's supporters are.

Pointing fingers is a necessary step in identifying the problem, and the problem is the system itself and the people who run it. You can't have infinite growth in a finite system. It's not logical, let alone possible. And since we are living in a patriarchy, yeah, I'm pointing fingers. It's not men individually that are the problem. They are subject to the same stereotypical gender roles as women. It's the archaic idea that men have to be the bread winners and protectors while the women stay home and pop out kids. It's great for the economy after all.

The American Dream died when Reagan was elected, but for some reason, it's still dangled like a carrot. The patriarchal society started when organized religion became a thing. The big 3 religions are patriarchal by nature. It's written in doctrine. They have a lot of influence in politics. Christianity specifically. God said, "take of the earth. Go forth and multiply." See? Capitalism is written into the very foundational teachings Christianity, a patriarchal religion, with more than their fair share of political influence. It's too much stress for the human psyche to handle, and now there is a nation of people struggling to live up to standards that are complete nonsensical fairy tales. Not a good thing for mental health.

Patriarchal Capitalism had its run. Now the world is burning and flooding at the same time. It's a failed system.
