I don't believe this take is fair or correct. FANG-like jobs are designed to depersonalize workers, compell them to work extremely long hours, force them to be constantly on and available, and basically live for the company, only to be pushed out of the company by design and get fired as disposable canon fodder at the slightest bump on the calendar.
The pay might be good, but it resembles a deal with the devil.
Have you ever wondered why the average tenure at some top tech companies is measured in months, and reaching a milestone like 4 or 5 years is lauded as a major achievement? I seriously doubt that so many people is just "externalizing their happiness". Sometimes it's really the job that kills you inside and does so by design, don't you think?
