Abstract
In the United States, the political future is constrained, for better or worse, by constitutional arrangements that have been in place for more than two centuries. Barring dramatic developments that few would welcome, such as nuclear war or major terrorist attacks, it is highly unlikely that the political system will change much over the next few decades.
In China, by contrast, the political future is wide-open. According to the formulation of the Chinese Communist Party (CCP), the current system is the "primary stage of socialism," meaning that it's a transitional phase to a higher and superior form of socialism.
The econonomic foundation, along with the legal and political superstructure, will change in the future. For independent intellectuals, the only remotely plausible justification for the current system of economic liberalization combined with tight political control is that it is a temporary necessity given the need to provide social order during the disruptive period of economic development (and many would reject this claim).
Nobody argues that the current political system should remain in place once the economy is developed.
