Ev came from an unusually humble background for Silicon Valley.
Steve Jobs was from Silicon Valley but grew up poor.
Reid Hoffman's mom hooked him up with vc money and a network, cause she was a rich lawyer at a fancy firm iirc.
Very few people that grew up poor are successful in Silicon Valley but they may be the most impactful as a population.
