> Elon Musk I believe also was the beneficiary of a small amount of investment from his parents.

There's so much mythology around this. I've heard the argument, "he had no support from his father", and I've read in more detail that one of the examples of said lack of support was "Elon and his friends wanted to buy and operate a video game arcade when they were teenagers, but his father refused to provide financial assistance".

There's a whole world between "deadbeat" and "wouldn't buy his son and his friends their own video arcade".
