One thing Elon Musk definitively proves is that assholes shouldn't be billionaires.
It's a bit chicken eggish to argue if assholes are more likely to become billionaires or becoming billionaires ends up compromising one's humanity such as to turn one into an asshole, but you just can't get around the fact that probably most every billionaire is an asshole.
And being billionaires enables a lot of power.
That is bad.
Tax the fuck out of those fuckers. Those assholes.
