There are a lot of concerns about China’s income disparity between costal provinces and inland provinces. Let me show you why we shouldn’t worry TOO MUCH about it (we do need to worry about it though, and we definitely need to come up with solutions; but don’t’ worry too much or go against natural laws).
Some stylized facts for our readers:
50% of World's population and 67% of World's GDP are within 100 KM of an ocean or a river that is navigable as far as the sea. In Japan, 97% of population live within 100 KM of coast. In Europe, 89%, live within 100 KM of coast or ocean-navigable waterway. The ratio is 65% for the United States.
Thus it is natural that income disparity will always exist between costal region and inland of China, because you are naturally disadvantaged if you reside in inland areas.
You will certainly question me: why is the income disparity that huge in China then? Americans residing in inland are relatively poor but the gap is not as large as that is found in China.
The reason is population density. Starting more than 1,000 years ago, Chinese migrated westward and southward for new lands, and eventually the population density in these new-found lands becomes as high as where Chinese were originated. So long as the population density in inland region is higher than what its geography can support, you will have lower standard of living there; At least you have to try much harder. American inland income level will go down substantially too if Mountains states have to support the same level of population density as in New England. There can only be several Las Vegas.
The only solution to this is migration of labor, as well as increase of accommodation capacity in already densely-populated costal area through better planning. In Japan, the government does manage to increase population density in Tokyo bay area without compromising too much in environmental protections.
For the past twenty years, high geographic and social mobility in China has been a great weapon in combating poverty and social unrest.
Believe it or not, most of China’s middle class and new rich were born in inland countryside. They left their stifling hometown and headed for costal cities. There are few opportunities in inland usually not because of high transport costs. It is more a culture thing, that inland people are relatively isolated and have less exchange with outsiders, as a result, through generation after generation’s cultural reinforcement, they become less open-minded and less flexible, which is very bad in today’s commercial world. Many inland Chinese who get successful in cities are unwilling to return because they really hate the gossiping and equalitarian culture back in their hometowns. Such culture really kills talented people.
Some leave by attending colleges in cities, thanks to the standardized college entrance exam which is probably the last area of the system that is not yet corrupted. Even the most totalitarian emperors in Chinese history dared not to abort or corrupt the exam system, because by doing so you are closing the route of social mobility and you are calling for grassroots uprisings.
Those who are less intelligent usually start as laborers in construction sites in big cites, save some money, start small businesses, grow bigger. They are advantaged because they are more hard-working than those born in cities, and can take any pains in the process (what kind of pains and humiliations can be greater than returning to their hometowns without getting rich)
Whichever routes they take, they settle in cities, and within one generation of sacrifice they place their children on the same starting point as those who were born in cities. We talk about American dream, and this is Chinese dream!
We rarely notice such high social mobility in China because once these country folks settle in cities they blend with the other people and most of them are unwilling to reveal their original roots. Most of them deep down still feel inferior.
This doesn’t matter though, so long as the system has provided paths for inland people to step up the social ladder. It is the fact that most senior officials in all levels of government and businessmen in the Forbes list of richest Chinese were born in countryside.
World Bank’s “ World Development Report 2006: Equity and Development” calls for equality, but isn’t inequality of wealth through personal hardworking more beautiful than equality of poverty through government intervention.
World Bank president Jim Wolfonson realizes this too, and write down some important caveats in the introduction page in case the message of the book get mis-interpreted.
"The history of the twentieth century is littered with examples of disastrous policies which were promoted in the name of equity or equality, and the results of which were ruinous. No policy that pursues equity without respecting market-based individual incentives for prosperity is likely to succeed. The joint pursuit of equity and prosperity must therefore be cognizant of the primacy of individual freedoms, and of the role of markets in allocating resources"
