You would think that someone out there would fix those problems at their companies and reap the rewards: an effective, highly motivated workforce.
The fact that we haven't seen that means either that it's a hard problem to solve, that nobody pays attention to it, or that there is no economic value in working to have "good" practices when it comes to workforce management.
... Or maybe it's good to have your workers living in fear, worrying if they'll be next at the end of your Kafkaesque processes ¯\_(ツ)_/¯
Oh, one last thing I remembered: a previous coworker of mine raved about how his company treated workers, but the company was later acquired by a bigger player, and the situation changed. Perhaps companies with good practices get absorbed by the "big bad wolves" that have established themselves in the market.
