The news that China has surpassed Japan as the world’s second-largest economy has generated a lot of attention. It shouldn’t. There are roughly 10 times as many people in China as there are in Japan, so the fact that total gross domestic product in China is now bigger than total gross domestic product in Japan is hardly a sign of Chinese economic supremacy.

Yes, China has been growing in recent decades, but it’s almost impossible not to grow when you start at the bottom — which is where China was in the late 1970s thanks to decades of communist oppression and mismanagement. And the growth they have experienced certainly has not been enough to overtake other nations based on measures that compare living standards. According to the World Bank, per-capita GDP (adjusted for purchasing power parity) was $6,710 for China in 2009, compared to $33,280 for Japan (and $46,730 for the U.S.). If I got to choose where to be a middle-class person, China certainly wouldn’t be my first pick.

This is not to sneer at the positive changes in China. Hundreds of millions of people have experienced big increases in living standards. Better to have $6,710 of per-capita GDP than $3,710. But China still has a long way to go if the goal is a vibrant and rich free-market economy. The country’s nominal communist leadership has allowed economic liberalization, but China is still an economically repressed nation. Scores have improved, but the Economic Freedom of the World report ranks China 82 out of 141 nations, just one spot above Russia, and the Index of Economic Freedom has an even lower score, 140 out of 179 nations.

Hopefully, China will continue to move in the right direction. That would be good for the Chinese people. And since rich neighbors are better than poor neighbors, it also would be good for America.
