Sure, fair points. We should distinguish good and bad managers here before we get too specific. The bad managers will do whatever they're told to do by upper management. Upper management just says "cut down to this number" and they do it because they only care about their own incentives and don't care about the consequences. The good managers will probably realize the downsides of these decisions and will try their best to blunt the impact of these decisions. But in the end, they still have to report to higher levels of management, so there's little that they can ultimately do. So they're probably going to end up doing the same thing anyway.

This is why management is such a hard position, especially in the lower levels. You're basically at the end of the chain and usually have little power to get what you want. At the same time, you still have to make lots of different groups happy - upper management, your workers and whoever you're delivering your product for. All the things that you listed are things that I'm sure they would like to have, but probably end up having to get sacrificed anyway. If there's only one group of people that you're going to please, chances are that it's going to be the people you report to.
