If we don't have a system for that, then how would you incentivize people to take on bigger risks, bigger projects, etc?
Also, should the lottery not be a thing? What exactly are you advocating by this line of reasoning?
Imagine that making a ground-breaking discovery in physics came with a prize of a billion dollars. One good idea, and you can retire. Would that not harm science? Many scientists would keep working after their first prize because it's what they love to do. Some would accuse them with being greedy after they've made a few more discoveries. "Hey, leave some money for the rest of us!"
What I'm trying to get at is that the rewards for certain things are badly out of whack with what is necessary to keep people both rewarded and motivated. At least, in terms of what is healthy for society and progress. In general, the closer people are to the money the more unreasonable the rewards are. Perhaps people who are further from the money but who contribute just as much (or more) to society are right to be concerned.
P.S. Musk bought companies with people who had a lot of good ideas and convinced governments (mainly the U.S. government) to pay for it. He's always been a capital guy, not an idea guy. He desperately wants to be in idea guy, but his ideas are things like re-branding Twitter to X and the Cybertruck.
Personally speaking, I am sympathetic to the idea that billionaires (especially Musk) are often created more by government policy than market forces. Although for some reason the push to stop governments minting billionaires by fiat seems rather weak, which makes me think a lot of people are being disingenuous on the topic. Or maybe just haven't thought about it much. There is a bizarre zeitgeist where first the government has to give a man billions of dollars because something needs to happen ASAP, then they have to take the billions away because nobody thought the thing needed to happen all that urgently.
There is an overlap in the vibe between the people who are unhappy that the government rewarded Musk and the people who, at the time, were clamouring that the rewards for things Musk was doing were too low. 10, 20 years ago it was all "there isn't enough funding for electric vehicles", "world is literally ending from climate change" and "who is going to put money into batteries".
The people closest to the money are the people who have the most control over how and who its allotted to. We really ought to watch them more carefully.
It’s rewriting history to call Musk a “capital guy.” Tesla and SpaceX entered markets with huge, established competitors. Those companies had access to virtually unlimited capital. But EVs and commercial space travel were pipe dreams before Musk got involved. I graduated with a degree in aerospace engineering pre-SpaceX and the field was moribund. Your options were going to Boeing to make airliners 1% more efficient every decade or going to Lockheed or Rockwell to design better missiles for blowing up brown people. The idea that SpaceX was just about a “capital guy” coming in is 100% hindsight bullshit.
You’re also just completely factually wrong about “most of” anything “coming out of government coffers.” The government gave Tesla a $485 million loan that was fully repaid. SpaceX received about $500 million in grants. In both cases, that was a small fraction of the money invested into the companies. Tesla’s cumulative net loss was $6 billion before profitability. SpaceX’s cumulative net loss is $42 billion.
At most you have a fair argument that the government should take equity in companies instead of providing grants with no strings attached. But that would just mean that maybe the government should have a 10% share of SpaceX or whatever.
