I’d love to have had parents who could afford to dump $1m into my fledgeling startup.

That he did proves he owes others for his success as much as his own wits and hard work.

Right, he owes his parents as established. They likely owe their parents, who owe their parents. And there were certainly others that contributed along the way may or may not have been compensated for that help. But none of these people had help from an amorphous group of "society", they had help from specific individuals.

So none of them went to public schools or used public roads or relied on a fire department. Probably none of them could look forward to social security or medicare.

Or maybe that's not correct.

Everyone on Earth owes some of their success to their parents.
