If you also bother to look back, this started over Axel, I think it was basically saying anyone with a mundane, low status job was getting paid too much.
From my POV there was no intent to point score, just to highlight that whatever "business" or organisation one is in, it requires a whole team of people to allow it to operate successfully, from the very lowest to the "revenue earners".
In the multi £m organisation I worked in, it was very apparent if say, the cleaners had not done their job properly or someone was sick, but certainly not the case if the unit manger was on leave for a few days or weeks. I know which was the most important for me carrying out my safety critical role on a day to day basis.
