College is useful for meeting PEOPLE (not just chicks). Note that Zuckerberg laid the initial groundwork for FB while at college, and probably met some connections that were useful to him there as well.
It’s also sad that the US puts a lot of emphasis on success in business, but not so much on basic scientific/medical research, non-I.T. engineering, and academic careers anymore. The world doesn’t start and end at I.T. entrepreneurship despite what some people may think. It’s a problem that the US lags behind the rest of the world in scientific research and in basic infrastructure.
