1/3 of China's economy remains state owned, which means they have been able to push through the worlds economic crisis with more state intervention than the US. Nearly the entirety of their heavy industry is in the hands of the planned economy. The free market inevitably goes through cycles, which every economist in the entire wold knows, no matter their ideological bent.
Let me reiterate. If you are going to unintelligently prance around with your free market slogans, at least accept the fact that they have, throughout the history of their existence, been extremely prone to massive ups and downs. They have also plagued society with poverty, crime, and corruption.
