another way to look at it is that management is a job with a set of skills, challenges, and rewards, just like any other, but as a civilisation we seem to have tied it to power and hierarchy, and made it something you need to be promoted into rather than choosing as a career from the outset (MBAs notwithstanding). maybe a lot of engineers would have gone into the engineering management path if they could have, and engineer was just seen as the more entry-level option.
