It's also true that a lot of the ancillary labor that goes into these companies is bullshit in someway. Like every boss having a secretary to berate, or the marketing department. They do work, but it's of no discernable benefit to society. Software engineering is an intellectual labor, and a potentially very valuable one at that. But it's best value is for building the kind of infrastructure that would destroy capitalism, so instead we do stupid shit with this labor.
