If your workers don't leave, enjoy their jobs, and do them well, how can you argue that's less valuable than Amazon worrying about running out of people to hire because they blow through workers like Patrick Bateman through homeless guys and coworkers? My wife just left a manufacturing company because of the latter attitude, and they're fucked, because she was the only person left who could operate a 50s era prototype machine (that happens to make the only dry test slides in the world). I'm fully aware this is anecdotal, but if that company had treated workers well, they wouldn't have to be asking people to come out of retirement to operate a machine. That's a loss of value for them.
