The trouble with PMs is that being the most political of the bunch, they also tend to get promoted into management in much greater quantities. Once promoted, guess what, they promote their own (because that's their social circle), and hire a ton more PMs, which then get promoted and hire still more PMs. Lather, rinse, repeat, until you've run the company into the ground, then move elsewhere (e.g. to Google).
