The Pirates have no Anti-Ideology. So why do they always get mad at you for running Wealth. Is this another bug seeing that in the original game all factions had an Anti-Ideology? Maybe it defaults to Wealth?
In my experience, the Pirates are very like the Spartans. Any value other than Power (or none) irritates them. Indeed, they use all the same dialogue blurbs as the Spartans...'weapons program' and 'grown fat and weak and now I will carve you up' or something very similar to that.
