Being wealthy has also a lot to do with being at the right place, at the right time, inherited wealth, and outsourcing efficiently.
That being said, do you think the majority of the predictions he makes in going about his every day business are wrong?
To get to the point Musk has reached, it seems to me that that would, over a lifetime, require a person making billions (?) of small predictions that no one ever hears about. I think it must be the case that he’s very good at making those kinds of predictions.
I agree with you that being wealthy does confer a great advantage to people. I don’t think it explains everything about Elon Musk and the success he has achieved to date.
To be clear, I don’t believe in free will. It seems like an error to me to look at a successful person and claim that they achieved their success single-handedly.
OP is discussing his prediction about the economy though.
