And I find this sort of posts bizarre. The argument that "we are better of today than we were in prehistory or the middle ages, so quit your complaining". Yes, things are better, but no, that doesn't mean we should stop wanting to improve. We have accomplished a lot, but we have not reached the end-all stage of human development. Societies are better than they were 500 years ago, but they're still pretty damn flawed. We can do much, much better.
