Increasingly, as the society becomes more industrialized requiring deep specialized knowledge, managers and people with capital often find themselves similar to muggles who manage wizards.
Wizards are incapable of organizing in public, because they have broken away from society, to gain wizardry in magic.
Muggles, on the other hand, do not understand magic, but they can deal with it as if it were a commodity or phenomena, to be traded with other muggles. They develop ability to collaborate, banter and tit-for-tat with other muggles.
Muggles can only understand magic through metaphors of their world, and often times they mistake metaphors for true understanding and make magical decisions without understanding magic.
