Like, if you work for the EPA or as some lab scientist at the FDA, are you still a prole considering you are being paid with the ill gotten gains of the American empire.
Honestly, I don’t see why US government workers shouldn’t be deemed proles, because that degree of moral abstraction could be performed on just about everyone in the US.
Public sector unions are (with the exception of law enforcement) generally good and the opportunity to participate in them as a state/federal employee is a genuine opportunity to participate in defending the rights of laborers.
