I'm uncertain if said populism is fake. Most of HN readers likely fit the stereotype that the author is attempting to project in this article.
But that's what he is making: a stereotype and only a stereotype.
His assertions read more like assumptions that only sparingly drew on sociological information. When he referred to, I believe, a single sociological tome, he only considered "elite" schools. He neglected those of us who did not attend Ivy League (UVa here and I was a miserable college student indeed) and those who did not attend college at all! Instead, he seemed to prefer to pick bones with his journalistic peers.
Living in Worcester County, Maryland for the past couple of years, I find that I did not understand the "Digital Divide" until meeting for myself children with no computer or internet connection at home. Are these children likely to become the next Bill Gates, Steve Jobs, or Mark Zuckerburg? I highly doubt it. Even if they have it within them, this environment does not care to foster those interests. Instead, the local "vocational tech" school seems to emphasize and curriculum involving auto repair and HVAC. This makes me sad. And it makes me just a touch more sympathetic to this clearly embittered journalist.
Bring on the down votes.
