They didn't come from nothing - Elon Musk was 'bullied' but was still fairly rich. Bezos may have been adopted, but his 'new' father was an engineer with Exxon, and he went to a relatively fancy high school ( https://en.wikipedia.org/wiki/Miami_Palmetto_High_School ), Brin is listed as an immigrant, but his father was professor of mathematics at University of Maryland, Brin also went to a reasonably fancy high school ( https://en.wikipedia.org/wiki/Eleanor_Roosevelt_High_School_... ). To me Brin, Bezos, Musk are far shots from the article's 'earlier' examples of people like Warren Buffett who grew up with unemployed parents.
