I don't think it's up for interpretation, the criteria is in the actual quote "who produce some thing valuable for the community". It could be any profession: researchers, managers, financiers, teachers, manual laborers. If they produce value for the society. And the same professions can be free loaders or even worse, suck value from society. The quote, as I interpret it, is about Price's law. Not about professions, social or economical classes.
