A journey through time and development - great video clip

The Economist have posted a terrific video that takes a tour along the Pearl River in China. As the scenery rolls by, the narrator comments on the extent to which the journey through the surroundings reflects a journey through China's recent economic development.

The video can be found here.

the supporting text says:

Nowhere are the consequences of different rates of growth clearer than on a trip up the Pearl River Delta in southern China. At the river’s mouth sits Hong Kong, a city in which average living standards exceed those in most rich European countries. Travel farther north and you pass the container ports of Shenzhen, behind which new skyscrapers tower over a sprawling melange of housing and factories. Since its establishment as a special economic zone in 1980, Shenzhen’s economy has grown at a frenetic pace, and incomes there are now just over half of those in Hong Kong, which is similar to what you would see in southern and central Europe.

Farther north and west sits Guangzhou, capital of Guangdong province, with its newly constructed motorways and tower blocks among the rice paddies. Average incomes in Guangdong are just a quarter of those in Hong Kong, equivalent to Algeria or Costa Rica. Finally, toward the western edge of the watershed, the tributaries reach across Guangxi into Yunnan—provinces where the people have yet to get into the flow of China’s voyage of development. Incomes there are but a tenth of those in Hong Kong, on a par with those in Angola or the Republic of the Congo.
