China’s economy is one of the fastest growing in the world, faster than any western power. Wealth is more evenly distributed as well, in terms of economic class. China’s major weaknesses economically are lack of rural development (which they are fixing) lack of ability to grow enough food or produce enough oil to sustain themselves (the food they buy from us and the oil from Russia), and the fact that the One Child Policy has worked too well, leaving a tiny generation to support upcoming boomer retirees. But every nation, more or less, is interdependent, and these are manageable problems for a country whose economy is almost doubling in size every ten years (AFTER adjusting for inflation) while ours is growing at an exponentially slower rate.
The thing to take away from this is that China’s economy, at the current rate of growth, will double in size every 10–12 years.
India better beware because it failed to match China and worse 40% live in poverty.
