In my experience, every company eventually gets led by a sociopath. Every worker has the same story about how the old boss was so good to employees etc and then replaced by some ruthless profiteer. Companies prosper (profitableish, lots of innovation, employees are first) under the former, and are eventually pillaged and killed under the latter.
I think our current economic/social climate forces the kind of gervais principle balance over a long enough timeline. The gervais principle generates predictable profits.
This mirrors my experience as well. In the small and medium-sized business area, the "sociopaths" are the large businesses and private equity firms looking to acquire the smaller businesses. Or often it's the business owner who's the only sociopath in the business, but they are far enough removed from day-to-day operations that the people working underneath them don't recognize them as sociopaths.
Another thing I've learned is that the more time you spend with executives, the easier it becomes to recognize this behavior. Go to any large chamber meeting in any large-ish city in the U.S., and I'm sure you will find plenty of sociopaths (in both the literal and the Gervais Principle sense).
