I’m scum for being born in this country
No, you aren't, that's imperialist thinking pointed inward. Now if you were to go sign up for the US military and work on technology for bombing people in other countries, that would be scummy. But where you are born is something you have no control over and thus cannot possibly be your responsibility.
Reddit third-worldists call me evil for being born here.
Try not to take it personally when people do this kind of thing. Anyone actually literally saying that is misguided to begin with, but it is probably coming from a place of hatred for the empire and what it does, rather than a preoccupied hatred of every single individual living in the regions it controls.
we’re all labor aristocrats
I think that is an oversimplified analysis. Is a homeless person a labor aristocrat just because they're homeless in the US? I don't think so. The labor aristocracy analysis can be useful for tracking the connection between imperial spoils and imperial worker seeing some benefits from it, and how that changes the way they think about class struggle and international solidarity. But it loses precision of meaning if it is applied as a blanket categorization to everyone living in the imperial core, which defeats the point of it being a tool for being more precise in doing class/caste analysis.

Not everyone, but certainly there is a lot of it. This is likely to keep shifting as people do what they can to educate and as conditions worsen, with the electoral system providing no real relief.
