Libertarians: Economics is important. And so is psychology!

Libertarians understand economics! This is true and it's a very good thing.

However, an understanding of psychology would be a useful addition to their tool set.

At a minimum, this kind of awareness would help them understand why so many of their fellow humans resist the idea of a truly free society -- and how those who would rule them have been so successful for millennia. And how they continue to "succeed" (the way the savages "succeeded" in chopping down the tree to get the fruit).
