Middle class is and always was just a third class aristocracy that preside over the stolen labour of the imperial periphery. That includes me and I imagine most Western Lemmy users whether we know that's what's happening or not. Maybe not as bad as the real aristocracy but very far from blameless for the exploitation happening in the world. Not wanting to live off the exploitation of others is not an excuse for it actually happening. We're all culpable.
I'd even go as far as to say there is no true proletariat in the imperial core because of how pervasively the spoils of exploitation is distributed here. The poorest person here still actively lives off the labour of even poorer people in the periphery.
