Elon Musk is probably at least millions of times more productive than the average human.
If you were to calculate the sum of gains and losses between Elon Musk and humanity, it would balance out that Elon Musk is overwhelmingly the creditor, and humanity is overwhelmingly the debtor.
As with the great-grandparent of this comment, your comment is a massive moral equivocation.
Musk would have a hard time innovating if he had to build his own house, grow his own food, knit his own clothes, etc. etc...
We all rely on each other to provide our basic standards of living.
Without our basic needs being satisfied, we don't have a platform from which to focus on innovation.
Yes, innovation is great, but don't act like they are the entire backbone of humanity.
