"...in white-collar jobs, the amount of work can expand infinitely through the generation of false necessities... reasons for driving people as hard as possible that have nothing to do with real social or economic needs."

You Really Don’t Need To Work So Much - The New Yorker: "What counts as work, in the skilled trades, has some intrinsic limits; once a house or bridge is built, that’s the end of it. But in white-collar jobs, the amount of work can expand infinitely through the generation of false necessities—that is, reasons for driving people as hard as possible that have nothing to do with real social or economic needs. Consider the litigation system, in which the hours worked by lawyers at large law firms are a common complaint. If dispute resolution is the social function of the law, what we have is far from the most efficient way to reach fair or reasonable resolutions. Instead, modern litigation can be understood as a massive, socially unnecessary arms race, wherein lawyers subject each other to torturous amounts of labor just because they can. In older times, the limits of technology and a kind of professionalism created a natural limit to such arms races, but today neither side can stand down, lest it put itself at a competitive disadvantage."

Moreover, our many improvements in the technologies of productivity make the arms-race problem worse. The fact that employees are now always reachable eliminates what was once a natural barrier of sorts, the idea that work was something that happened during office hours or at the physical office. With no limits, work becomes like a football game where the whistle is never blown."
