Competence is a spectrum. I've worked with managers who would listen, and nod along to problems I was pointing out, and after the meeting nothing would change.

It's very much a communication issue, but also an incompetance political game playing issue. To answer your question, I put a ton of energy into doing exactly what you suggest, which most people didn't and don't. It ammounted to some changes eventually taking place after I left, according to my former team members, but the managerial nonsense never dissapeared; those managers involved were later promoted.
