I'm not sure arrogant is quite right - it always seems to me to include an element of conscious decision to assume one's own superiority and look down on lesser mortals. I think some of this lot are so much in their bubble that they are not able to do that. It's related to the word arrogate, isn't it, which is to take power appropriately?

Haughty, maybe. Autocratic? I've been looking in the thesaurus, and all of the suggestions do include that element of deliberation.
