It's true that not all of us are the entrepreneurs in this world, but why should such people get paid ten thousand times more than people who are equally skilled but skilled in different areas? And it is ridiculous to assume that people who are not company owners don't work hard. It takes more than one skill to make a big company work. What we are doing at the moment is rewarding certain skills out of all proportion to others.
No one is assuming others don't work hard, this isn't necessarily about skill or hard work - that is somewhat missing the point.
Instead of a business owner consider perhaps a pop star - Taylor Swift for example... she doesn't need be the most highly skilled singer out there, or the best dancer etc.. there are likely better skilled singers who aren't pop stars and work as backing artists etc.. she's likely got a bunch of dancers in her tour group that are better trained than her. all her singers and dancers and the musicians in the band supporting her put in the hours in rehearsals, performances, they're all on tour together... but she gets the big $$$$ like massively more than any of them (or indeed all of them put together).
Likewise Elon Musk isn't the smartest person in the organisations he part owns or runs, that isn't why he gets the big bucks though.
Now, don't get me wrong, I do believe that entrepreneurs need to be rewarded for their special skills. I have no issue with people earning millions. But I have real issue with people
earning billions. It is not jealousy. I am not jealous of people who earn millions, why would I of people earning billions? It just seems totally immoral to me. When people in this world slog their guts out to barely earn a living wage, it can not be right that anyone can earn hundreds of thousands or even millions of times what they do, just because they have different skills.
Why isn't it right though?
Say one of Taylor's backing singers is also a song writer, they're a really good singer perhaps - maybe they are able to get some gigs in small venues, maybe they can get paid to sing at weddings etc.. the fact is though that people aren't as interested in listening to them. They might make more money supporting Taylor on tour.
Likewise some AI researcher might be able to set up a small company, make a bit of money doing some consulting... or perhaps they could launch a product or mobile app and make a few $$$ though in plenty of cases they'll probably make more working for Elon on a fat salary and with stock options/RSUs
No one is stopping either the backing singer or the employee research scientist from doing their own thing or trying to.
Why does Taylor get the big bucks - because she's the reason everyone is there, she's the reason they're buying the tickets/albums, she created this stuff, it is her music, her songs etc.. no one gives a **** if some random backing dancer/singer/other "employee" gets sacked and replaced with an equally qualified hire, they're not the reason for the $$$ coming in and there are more of them out there.
Likewise in a large company most individuals are completely replaceable.
You get the big $$$ if you own a stake in the business and/or a stake in the profits/sales. In the case of Taylor, only she really owns a stake (or at least now - in the past some music execs owned a chunk too).
In the case of Elon and his ventures - early stage employees typically will own a chunk and there will be plenty of millionaires and multimillionaires who have benefited from working with him, they took a risk too. Once a company is larger and more established then it's perhaps less of a risk - why would anyone just handover millions to a developer joining Tesla today? They'll pay you your market rate... that will probs include equity and if the company does well then that equity increases.
In some traditional businesses like law and accounting firms becoming a partner is where you get the $$$
Re: a stake in the profits/sales - you don't necessarily *need* to own a chunk of the firm either as a partner getting a nice revenue stream or a tech company early employee or founder benefiting from growth - a salesperson might have a deal where they are given a % of sales as commission, if they perform disproportionately then no reason why they shouldn't be rewarded disproportionately - they've brought in the business... You can see similar with traders for example - in the oil industry there are even guys who are salaried and earn more than the CEO of their company in bonuses etc..
