It gets more complex of course, I work in a kitchen and the chef works the line just like the rest of us in addition to other responsibilities for very little money especially cause it's salaried when you're 'management's he's making less than he would with hourly. On the other hand he can fire us. I think in class theory the class traitor aspect is what really matters, but with the general lack of class consciousness, that middle management is usually a pretty shit gig as well and all that, the specific people in those positions aren't generally the ones to be upset about as people. Capitalism organizes people these ways and while some are for sure gonna end out as open class traitors the rest are just people trying to have an okay job who probably don't need to be shot. What lies where depends on the discussion at hand.
