In recent years, a dozen times I was in China and I have to say that such places like Shanghai and Hong Kong making a great impression, but you have to remember that nowhere in the world has so blatantly rapidly progressive social stratification. Combination of an aging generation of people from "one child policy" (today they are over-50s) and a lack of a pension scheme, means that in China we are dealing with 300 million inhabitants city from which half live in a decent economic level, but the remaining one billion of rural population live in terrible conditions and is only a reservoir of cheap labor. Huge demographic problem. This situation is somewhat rescued by massive investments in infrastructure, but it can't save high economic growth, which is the only thing that saves this country from collapse. If you add to this environmental disaster, picture is not optimistic.
In murica, it is much better. Shale gas and energy revolution (very cheap electricity) in US already attracting big industry from China and Europe.
This will keep NA on the wave and China will significantly slow down.
Waiting for an economic union EU - NA. Great business development prospects for our businesses.
