That’s not what I’m talking about, I meant, say, helping those similar to you with the implicit idea that they’d help you too, and that being a common rule in a certain subset of the society, thus working.
Can’t remember now why I chose that word, “corporatism”. (Not important for the subject, but Knights Templar or any trading family or clan that would exist before 1400s can still be called corporations, same for religious sects.)
