treatlerism is a manifestation of labor aristocracy in my opinion. in other words, labor aristocrat refers to the class position and treatlerite refers to the specific ideology of the class. the difference in practice is that you can be a labor aristocrat without being a treatlerite (if you are a class traitor) but you can’t be a treatlerite without being a labor aristocrat (because you can’t get the treats)

I’m not much of a theorist but in usage, it seems like the former participates in building and upholding the system while the latter is bamboozled by and enamored with the system

From what I’ve heard they sound like the same thing.
