I thought it was a bit harsh to not include Spain in "The West", but I think you'd be splitting genetic hairs if you wanted to consider the average Spaniard a different "race" to someone like Yegge.

I also think your claim is not substantiated.

Also too add my own anecdata, this "cheat if you can - screw over the man" is a huge part of Spanish culture. That's not to say it's how everyone thinks, but every institution tries to check you're not cheating them, and of course still gets cheated.
