This is a good summary.
Sooo he got his wealth from Gov't handouts and other big-shot companies. But he's using it for SpaceX who's ultimate aim is advance civilization and save us from ourselves. Would you rather the Government or Google kept that money?
Surely it'd be more of a problem if he was using this wealth to buy himself Beverly Hills mansions and roll around on yachts flaunting his cash.
He purposefully tanks the corrupt stock market and makes ludicrous offers to disrupt billion dollar companies like Twitter. It seems pretty clear to me preserving his personal wealth and cash isn't his priority.
He seems like everything a progressive would like.
In all honesty how the * are you supposed to change the world in this fashion on such a scale without having billions behind you?
