This is a romantic vision that the companies themselves like to perpetuate, but it's no longer true for a decade or more. It's irrelevant what the Facebook employees think, just like it's irrelevant what the employees of McDonalds think about the health of their customers. They are not unique, precious snowflakes of rare skill, they are replaceable cogs in a machine that exists for a single purpose, profit. Massive IT education programs now underway everywhere in the world will ensure that the corporations will have vast masses of foot soldiers so they can concentrate on what matters: creating competitive advantage and market dominance using the strong network effects technology affords.
Silicon Valley has bred an ultra-aggressive type of capitalism that will crush and automate the old competitors away but will no longer redistribute the wealth to the workers, as capitalism has done for the last few hundred years, because it no longer needs them. In this economic war, developers are rich mercenaries, not noble freedom fighters. The likes of Facebook and Uber are simply the expression of that social reality, a glimpse into the world of tomorrow.
