The "scumbags" you describe are the ones that exhibit a strong "need for power" as described by McClelland. Engineers tend to have stronger "need for achievement", eschewing the power grab.
But organizations today and perhaps in the past have always rewarded those who attain the power. Perversely, if you want a place where achievement (ie doing the work, building things) is rewarded properly, you need someone with that mindset to suck it up and win the power game.
