Silicon Valley has spent years setting itself up as an inheritor of the counterculture, a place where it's possible to "think different". Employees are given a share of the business (via a complicated tax shelter of options). Startups want "contributors", people who buy into the idea that they're engaged in a positive-sum contribution to the world rather than just bringing home a paycheck. They provide all sorts of office features to encourage people to "bring their whole self to work".
