It's dehumanizing and unsustainable -- any job that sets a pace you can't keep up until retirement (i.e. 30+ more years) is overtaxing you. Not to mention the lack of psychological safety -- no point befriending anybody at work if you're all interchangeable at a moment's notice.
I think to turn this trend around we need to say "no" to places that treat you this way, and not glorify them simply because they are big (I'm referring to the F-word).
