Nobody denies that Musk family was wealth. They were wealthy because his father was a successful engineer.

And at one point his father made a small investment in a mine. And even that is grounded on shaky evidence.

This mine investment might have been profitable (we dont know) but the idea that his family had some waste emrald mines is nonsense and that investment certainly didnt make the family rich.

And given their bad relationship, Elon lost support from his father when he came to US/Canada.
