I definitely took it to mean that it was a (perhaps small) positive correlation and not an immutable law, but maaan. At this point in my life I might think it's even a negative correlation.

I'd like to think that a benevolent sort of mutualism is kind of an obvious higher truth. I certainly believe in it. If we work together there will be more for everybody. Very few things in life are truly zero-sum.

And I think for most of human history, things worked this way. In a small family/village/tribe, cooperation was essential, and there was probably a pretty strong evolutionary preference for those that were benevolent rather than evil, at least towards their own family/village/tribe. Smarter people would understand this better. Help your neighbor out, and he'll help you out, and maybe nobody has to get eaten by a bear.

But no more. Groups are so big now. There's no obvious personal benefit to being a "good person." If you act like a dick in a small village then maybe you die next winter because the grain never gets harvested and everybody starves. But in modern society, there's just not much of a penalty for being a dick.
