In all fairness, it also assumes that:
1) workers actually have something to do other than answer redundant (sometimes unanswerable) questions all day,
2) they are not waiting for f**ked up source-control systems that go down, or take fifteen minutes to finally come back every single time you want to change something,
3) they spend good chunks of their time doing mandatory web-based "training" in which the proper answer can always be ascertained by asking one's self, "In this situation, how do I not behave like a dumbsh*t?",
4) they don't spend hours in back-and-forth emails about the specific shade of a hideous orange color that matters to no one but those who are color-blind,
5) their lives are seven working days of sheer boredom, punctuated by seven hours of furious productivity (and this is considered an amazing amount of work by Big Three standards),
6) said workers spend hours creating things, and spend months waiting for approval to implement,
7) that their products work so well that, by comparison to the other stuff around the Big Three, they have zero problems.
If I could, I would tell you stories that would make you shake your head in bewilderment.
