Other than perhaps space exploration, what do any of these have to do with physics? It seems what you are arguing for is “just found multiple highly successful businesses”, which… well, yeah. Why do you need a physics degree for that?

I think cars have something to do with physics(like most real things), and since physik is applied math and being good with applied math might also help with numbers of money in general, I think a physics degree is helpful in allmost any job.

Physics seems to attract the sort of people who have the sort of arrogance it takes to look at a product or business and say "This is not great. I can start work from first principles and build a better one". Elon Musk is certainly an example, but not the only one (think MySQL/MariaDB, 90s Nokia, or more far-fetched example, the Red Special guitar). Physics also tends to be just difficult enough that most computing or finance problems are easy in comparison, and some of the math is useful.

Historically, the most successful examples in each of those industries have a physics degree. I cannot explain the causation.

Elon Musk also drives the mean for physics majors way up.

Ah, "mean ROI". What's the median ROI? What does the distribution look like?

I have no clue.

It was supposed to be a joke, which maybe people missed, about how Elon Musk was a physics major and how mean values on power law distributions are distorted greatly by the outliers.

So I have n clue what the median is, but I assume, like all income and wealth distributions it follows a power law distribution.
