I think the point is the only evidence that you provided for the argument that “Musk got his wealth from his family’s emerald mine” is that his parents paid for his college expenses. And that is, in my and many others minds, is a pathetically weak argument.

Full disclosure - my parents paid for a lot of my college expenses. At least half of the people who go to Ivy leagues have parents that will pay for their college expenses. It’s almost entirely, if not completely irrelevant to his work at PayPal, the founding of SpaceX, and the building of Tesla.

So it’s baffling (to me, at least) that it keeps getting brought up as a reason to hate Elon Musk. It feels that people want to find reasons to deeply hate this person, and they through anything they possibly can against him, nonsensical or not.
