The last thirty years are the last thirty years, as Ian Bremmer observes:
While it’s a good sign that the current leadership is allowing lower growth rates in order to implement some economic reform, thus far all changes are happening inside the system, not to the system itself. Easy growth was the low-hanging fruit for China over the past thirty years. Now the government is reaching a bit further up the tree. But they still have a very long way to go to get to the upper branches.
