There are many ways he could do that. But that would require self-reflection, humility, a willingness to admit his faults, accepting that his critics were correct, and so on. He doesn't want to humble himself and rebuild, he wants to conquer and crush those who are not completely subservient to him.
It would probably also require him to roll up his sleeves and do some hard work on his own, instead of building a brand off of the unpaid efforts of others. I'm not sure he can do that, even if he somehow gained enough self-awareness to realize what a lousy person he is.
