Will Smith’s actions prove that there is something more than poverty that causes violent bahavior. He is a violent thug.
Watch Bill Burr Gold digging Whore routine and you'll understand what's going on here. Poor Will has a lot of bundled up anger due to his "open marriage". He let some of that rage out on Chris rather than slapping the shit out of his wife, which would be far more expensive.
That was not staged. Anyone who thinks it was needs to get a grip on reality. Will Smith will lose his academy award and his wife. She will realize that he is a loser and leave him over this.
