b) I typically regard such actions as means to sustain profit, but I won't deny the exceptions to this rule.
c) I scrutinize the definition of profit here, but I won't disagree with what I believe to be your sentiment.
You go on to describe the feudal and individual capitalist (I think?) modes of production, which helps to define profit, but this is otherwise divergent from (c). In the communist mode of production, "profit" serves the community (ideally global), not the individual. I'm wondering what your profit analysis of the communist mode of production is.
