China has a population of just over 1 Billion people, and about as much real estate as the lower 48 states. The level of poverty is staggering compared to the USA, and the communist government is just now loosening up enough to allow a middle class, thanks to our demand for cheap products.
Keep in mind that the reason for China's "one child per family" rule is to prevent the inevitable population explosion. Women are second class citizens, hence the export of girls for adoption by Americans. The reason for bringing this up is that there will soon be a critical shortage of natural resources to support the growth and modernazation of China. The price of oil will double to $200 a barrel as we are outbid by China with our own money that bought all that cheap stuff. The people there are tired of riding their bikes to work, and GM is now building cars for them. They can't make enough steel or concrete to keep up the pace of modernization. When they run out, they will not have the materials to expand the infrastructure they need. Nothing like driving to work on a dirt road.
Now substitute the name India for China. Guess what, they will have the same problems, except that they have more people with less government, so corruption is even worse than China.
As the Chinese like to say, "May you live in interesting times".
