In countries like Afghanistan, the corruption is in your face. In Nigeria, I heard of judges making sex the bargaining chip rather than money. Now let's put that in the context of an honor-based society. Imagine that you're the brother of a woman who got raped by a judge to have her case heard in court. What do you want to do? You want to kill the judge. So here is an insurgent movement that hands you a gun. You have rage, and they give you an outlet for your rage.

Corruption is a fact of life in America as in Afganistan, but as American citizens, if we are white, we tend to experience it as an opportunity cost. I live in Washington, DC, where the city council is notoriously corrupt. But how do I experience that? Maybe in streets that are not as well paved as they could be, maybe in a bridge that costs a lot more money than it should have. That's a little bit abstract - shocking, of course - but still abstract.

I know it sounds old-fashioned to say we're too materialistic in the West, but happiness does not derive exclusively from things, and yet we seem to be structuring our whole society around things. I think that's partially why Westerners are joining ISIS and going to Syria. We have lost our way in the West in holding up a vision for humanity that is not exclusively shaped by materialism.
