That's assuming that people in free countries are happier than people who aren't in free countries. "Free" is a nebulous term, and alot of people are happy just to be "free" to live their lives with their families, producing children and resources like their government wants them to. Does being free to buy the things you see in advertisements really make you happy? Does it really matter if your freedom is taken away by governments or corporations?
Well, at least corporations can't draft you into an army and send you to war. But what government can't?
