This is going to sound ignorant/stupid, but how is he so rich?

Tesla isn’t a huge car brand compared to the likes of Ford, Renault, Volkswagen, etc. They’re big in the EV space, but we’ve been waiting over a decade for an affordable EV from Tesla and all we’ve got since then is just nonsense. Obviously he’s been getting huge bumps from his position, but how has it only made him so rich? As an aside, how the fuck hasn’t the rest of the Tesla board not sacked him yet?! His last contribution was the Cybertruck, and his next step is literally to suck ALL profit into a dividend payout for himself. What viable business does something this stupid?!

I just don’t get how he’s so rich. In a sane world, the Tesla board would kick him out and put someone more devoted to the brand in charge.
