The title is deceptive because shortly after asking that question in the article, the author comes to a resounding "no" and goes on to talk about why it is our impression that SV only works on the problems of 20-somethings. The core of the author's comment comes at the end:

"Imagine how odd it would be to read an article saying that the people who work for manufacturing firms are really just out to make money, or that they don’t seem interested enough in current events. It is only because Silicon Valley has done such an extraordinary job branding itself that articles about their social conscience, or lack thereof, seem completely reasonable. But the tech sector is, on the whole, much more like other sectors of the economy than it likes to believe, or than it likes anyone else to believe."
