Lets face it the only realistic way for people to live together is what we see right now - wars, bitching, whining, stealing and all the rest. If you don't look at it through idealistic rose tints then it's ticking away quite nicely when it comes right down to it. The complex chunks of protoplasm are still vetoing the higher intellect in most cases so that, although in theory it's better to cooperate, the governing dynamic is "Skullfuck thy neighbor and take his molecular possessions".
It's fun, it's vibrant and it exciting. Of course if you're too attached to intellect it becomes depressing - that's the downside of evolving ahead of the pack. It's going to take your average bald ape another couple of hundred years at least before they get to where you are. So my advice is - drop the idealistic moral crap, if you see one coming toward you shoot first and ask questions later - you live amongst a pack of highly aggressive primates.
