I'm not the right person to answer this question.
My initial comment was an attempt to illustrate the fact that startup funders and VC's that get rich don't make innovations in a vacuum. They rely on a complex network of global labour, government funding, university research and the entire history of human knowledge.
Therefor I don't think funders and capital owners should feel so certain about their privilege to extract enormous amounts of private wealth for the prize of rising income inequality.
My question was: In building the Internet we use today, how much money was spent by governments, and how much by private industry?
