The thing is, he is bitching about all this stuff in a very raw manner. Completely unpolished, and yet it skyrocketed to no. 1 on the billboards, showing that people are tired of self-promoting narcissistic "artists", which are the vast majority.
And I say again, just about no one has the balls to point at the elephant in the room, which you didn't comment on at all. It's not about others being rich for their own pleasure. It's about them using their assets to control others. Human trafficking is a gigantic problem, the 2nd most lucrative business in the world. If you aren't addressing such a problem while being in power, you are (IMO) supporting it by not doing a damn thing about it.
This naturally leads to lots of suspicion towards those whose lips are sealed, unwilling to talk about it. Human trafficking is not little fly buzzing around, it's a frigging elephant.
