the analogy seems useful:
* China has the more united and disciplined central government, while the US had a more federalized, decentralized government, approximately like the EU.
* China has based its economic growth on exports, which is far less true of the US (and EU excluding Germany)
* China does not guarantee many (or any) economic rights to outsiders within its boundaries, whereas the US does. similarly the EU grants relatively strong rights, including government financial assistance and medical care, to outsiders within its boundaries
the simplest prediction is that it will turn out roughly the same way as it has for the US, and Germany, the EU zone's current main exporter, has the most to lose.
Much of China’s remarkable growth between 1978 and 2000 can be explained by the reform. But the more recent and faster growth in the last decade has been mainly driven by exports.
