ok here's why 100% pure laisez-faire capitolism is bad.
IF it weren't for socialists Thomas and Martha Wayne, Gotham City would have crumbled through the power of overwhelming economics as forseen by Raz Al Guhl. If that had have happened, then with Gotham's distruction so too would have fallen the entire Wayne family not just Thomas and Martha, thus Bruce too, and with the fall of Bruce Wayne as a child there would be no Batman... and let's face it, Batman kicks ass!
Therefore with 100% pure capitalism there would be no Batman, and let's face it "Flame of Liberty" do you really want to pass Batman off?
