Agreed in a lot of circumstances. How many bad managers think that yelling to get things done is actually accomplishing something on their part? Good managers have the ability to shepherd their people and resources in a way that gives them a better chance of success and minimizes the potential stumbling blocks. It still requires good people, clear goals, and lots of other things that may or may not be 100% under your control, but even with those caveats, you can generally assume that you'll have a bit more control in management, though parts are more indirect (you're not involved in writing the actual code as much if at all depending on the company, etc.).

But it's really easy to over-estimate that control and your ability to wield it. If the Peter principle is accurate, and people are promoted to their level of incompetence, then it also indicates that people assume their level of competence is higher than it actually is. And then you get project failures, screaming managers, and lots of lost money.
