Well yeah. Professors are like business unit leaders/managers, acquiring funding for research and setting the main outline of what to do. Then the others (usually, although not always, designated 'administrative staff', or grad students/post docs) execute the work. I'm not sure I would call them 'real workers', that implies that others (i.e., managers) don't do 'real work'. I mean I understand what you say - you mean 'real work' as 'producing something', but 'creating the circumstances in which others can produce something' is also work.
The thing is its always easy to see who 'produces something'. When you start talking about 'creating the circumstances', you trigger of a chain of helpers, who help helpers, who ... and so on. Until you arrive at a point where there is a whole hierarchy of people sitting just to approve things, keep records and pass memos.
That's often how it works these days. Means the university can keep most of the workers on lower pay scales and avoid having to grant them tenure.
Also I doubt if it is a case where researchers just perform the main rituals and others do all the remaining work.
If that is true, then your researchers are effectively managers here. The real workers are lab techs, programmers etc.
If we have to do this, lets put the saddle on the right horse.
