But you can't deny the fact that on the whole we're living better today than a hundred years ago and still better than a thousand (or even ten thousand)!

From your position (corrupted power with people crooked and selfish here and there) it would be hard to explain...

Actually not at all. I'll just say that we're better off in spite of there being government, not because of it. The improvement of life conditions has been arguably due to technology, not politics.
I'm willing to concede, that maybe government has been necessary throughout history, because there was an absence of other forms of organization. But now that it has gotten us to the point, where we have the INTERNET, its usefulness has expired. We can now manage our affairs much more efficiently on a p2p basis. Bitcoin is in the process of proving this right now
