Let's see; Musk is demanding that the board give him a 56B pay package.
Tesla seems to have about 130K employees. They could afford to give every employee a 400K raise and Musk still gets a fortune from the left over money.
So money doesn't seem to be very tight there, it's just that greed demands that a single person gets it all.
Employees can (and most often are) paid in those company shares as well, so no difference.
Employers (and employees) generally have a pretty good idea what the market price is for a particular job. If they have to fill 100 positions and offering $25/hour causes them to get 100 qualified applicants who accept the position, they could offer $35/hour, but this is like saying that the employees could accept $15/hour when another employer is offering $25. Some explanation is required for why they would.
So then we're back to it being a competitive market. If the company gets e.g. $60B in value from having Elon Musk, and he knows this and demands $56B, the company can either pay the market price or have a net loss of $4B relative to the alternative. And then have even less money to pay employees.
Or maybe he isn't worth that much and if the shareholders give it to him then it's costing the company money. But then that's maladaptive and the company will lose business to some other company that pays its executives less and uses the money to lower the price of their cars and gain a competitive advantage while still paying the market rate for other types of labor.
Either way it doesn't change the market price for those other types of labor, which are much easier to estimate than the value of certain unusual executives.
Well, if you're following that drama, that is how it is supposed to work and how the Delaware judge said it needs to work.
So, now Musk just want to move the incorporation to TX, where he can order the board to pay him whatever he wants without oversight.
