Power differential is everything. Jobs and Musk founded companies. They were always the boss. The boss can afford to be belligerent. Can employees afford that?

Here's my question: Did Jobs and Musk allow their employees to berate them as much as they berated their employees? If so, then good for them! But I suspect not, in which case, they're just hypocrites and bullies. If some belligerence is required for success, who gets to succeed? Only the boss?
