A lot of great thinking you have shared, which I don't think I can meaningfully add to, but I did want to respond to this:

I don't think the people living on Turtle Island need to go into destitution or something in order to cease being imperialist.

I didn't do a good job explaining what I meant there. I should also mention I wouldn't claim to be educated/informed enough to apply Marxist analysis with any accuracy or rigour to my daily life. I just happened to read and click with Settlers so I wanted to comment on this post.

What's scary is the unknown more than anything. My life right now is privileged without a doubt. But it didn't start that way. I think the fact that I've somehow fluked my way from lumpenproletariat (*) to professional managerial class (I'm an engineer) makes me sympathetic to Sakais analysis. I was a teenager during the militarization of the 2000s and read Marx at the time but as I got older what really radicalized me to the need to end imperialism was really seeing how meritocracy is an insidious lie. I therefore went into reading this text already agreeing with the premise without knowing it.

The unknown comes from not really being able to understand what parts of our lives will change. I don't think there will be scarcity or anything like that in the long term. Maybe it's useful to compare to the idea of Land back. It can be a scary thought for settlers but comes from not understanding the worldview of the indigenous communities and how fundamentally different the view of land "ownership" is. I still haven't wrapped my head around it fully, but it's something I'm working on better understanding so I understand decolonization in my local context.

Additionally, I've managed to embarrass myself more than I want to admit with an unconscious paternalistic worldview. Some of my work gives me the opportunity to interact with engineers from parts of the world heavily impacted by imperialism. Think: areas still struggling to establish Water, Sanitation, and Hygiene infrastructure. They don't need western engineers for technical reasons, they need us to work to undo structural problems like the funneling of surplus back to the imperial core.

(*) I have massive problems with the concept of the lumpenproletariat. I can accept it's a product of it's time and life experiences of those who developed and introduced it and has some use in describing the challenges of achieving class consciousness. It was a convenient word to capture my experience with disability, and the anti-intellectual worldview of the community I was born into. But I don't want to use it uncritically!
