The right answer is of course progresses of science and technology.

Before the Industrial Revolution, British had already a good economic and politic systems for over 500 years--let's count from the Magna Carte; the Glorious Revolution is less important. But so called "market economics" alone could not make Britain very rich and powerful; they have to wait the break after the accumulation of new technologies.

Even for the things in China in the recent 30 years, the improve of peasant's life in 1980s is not only due to the termination of Maoism; it is more contributed by the new agricultural advances (say, Yuan Longping) and the large production of chemical fertilizer.

But Zhang's some basic points are right, though he was not able to speak more obviouly: the CP goverment is the reason instead of the solution to the question why "market economy" is not ideal in China.
