A lot of managers are threatened by experienced people because experienced people are a lot less shy about pointing out bullshit. People with 5 or less years of experience are much less likely to have a backbone. They're still getting over the school conditioning to complete whatever BS assignment needed to get the grade. Many managers would prefer to have an apparently smoothly running operation than have honest feedback. I once worked on a team with several people with 20+ years of experience. We got new management that did not appreciate that the experienced engineers were pointing out that pixie dust doesn't actually exist. They ended up "greening" the team. The new, much less experienced engineers that were brought on cranked out the code and learned lots of skills, but the product ended up dead within a couple of years. Those managers all got promoted though.
