Perhaps in industries where regulatory environment is extremely rigid, it’s my hunch the founders must quickly fall in line or they’ll be cast out. Pharma comes to mind here, but I could be mistaken. In industries where there is this sort of “old boys club” or “wild west” mentality, such as exploration/mining or even video games, where the regulatory environment tends to turn a blind eye in many cases, (c) will take over in most companies, even the large ones.
I am particularly confused & conflicted when thinking of the financial sector. Most large banks you would think would be mainly controlled by (a) and (b), however, it seems like in the world of finance, (a) and (c) aren’t much different when greed takes over! Netflix Dirty Money episode on Wells Fargo comes to mind.
