Celine Dion doesn't show up, people want their money back. Some third bassoonist doesn't show up, they don't even notice probably. (...) So hierarchies are perfectly valid, perfectly fine. In fact if you're not in a hierarchy, it means you're not doing any division of labour, you're not having any pyramids of efficiency, you're not having any specialisation and you're in the stone age.
