There's been talk about the severe trade-imbalance between the West and the East. In short, dollars are not real, and the East is producing most of the real artefacts of the world now by far, very little is being made in the west, and some say that has disaster written all over it.
William Gibson the writer commented about how we are living in the West in a "post-industrial" society. And that is clear, the bulk of the industry has moved out of US and Europe. And like he says: if we no longer make things, what is it we do, exactly? And whatever it is, is it sustainable in the long run?
