They rely on a constant influx of gullible, industrious and ambitious people willing to jump through hoops for a bit before they get averaged into the grey mass of middle management.
Middle management is a scam where you let your eager workers feel they got somewhere but then get stuck for 15 years going nowhere because it mathematically doesn’t work to keep promoting everyone.
And you can’t promote people anymore who aren’t women minorities, anymore.
So then you have to clear cut middle management, especially if white and over 40.
The layoffs are basically a cover to do exactly that.
Then they refill the buckets with new dumb industrious people and ring another 3 years before doing it again.
It’s a talent Ponzi scheme and works everyone. And it only works with regular layoffs.
