There are many CEOs that are willing to work with others, it's just a matter of how much one is willing to delegate and place trust into the power they transfer. In Trump's case, he's a close-minded individual that, if we really think about, is not fond of delegating power unless his minions do his bidding and therefore, must have absolute obedience. Otherwise, he has no trust, even if they propose something better.
But I don't need to remind you of the dictatorial people on the left now, do I? I'm sure you're aware that one having authoritarian views is not limited to just capitalism, but also socialism and communism; it all depends on the individual.
