Yes, I was responding specifically to that and specifically about management. Managers do a hell of a lot more than most coders give credit for.

Where do you work? I've rarely experienced this. Current and last company, both fast moving adtech firms, we are always desperate for good managers. BUT the key is only to have managers with, well, management skills. That does not mean promoting the best engineers to management, a common problem. In fact it is often specifically not that. They get promoted in the tech track.

The book "Managing Humans" is worth a read if you're so cynical about managers. Though the actual problem is corporate culture in my experience.
