Recent reports of China’s economic growth contrasted with the U.S. economic downturn have left Americans increasingly concerned that China is becoming a new superpower, controls American finances and will surpass the United States as the world’s leading power. The reality is that the fundamentals of the American economy are stronger than China’s, and U.S. prospects are better.

Let’s take exhibit A. It may appear that China contributes the most to world GDP and leads global growth given its 10.7 percent growth last quarter, as well as its 8.7 percent average growth last year. However, that’s not an indicative measure of a strong economy.

Aside from the fact that China’s GDP numbers are illusory (largely because of how the country calculates its GDP), a significant portion of the growth China is experiencing is not creating wealth, it is merely taking it from other countries. In other words, Chinese growth is partly the result of detraction from, not addition to, world GDP, which means much of its success is dependent upon others.

This is because of the way China’s economy is set up. China  relies on its trade surplus with the rest of the world as the lifeblood of its economy. It exports vastly more than it imports. Seen in this light, China sucks GDP from other countries in addition to creating its own. Therefore, while it may be leading the world in GDP growth, to a notable extent these GDP gains are the result of China using the world to boost itself higher.

That does not mean, however, that China does not produce anything. To the contrary, over the last couple of decades, China has contributed to the world economy. While China’s production has historically met consumer demand to keep prices low around the globe, the world-wide recession is now causing China to oversupply due to weak global demand, which could lead to deflation. This is hardly an indication of a sound, robustly-growing economy. If China does not start developing more of its own domestic economy for its people, trouble looms.

Further, China is not America’s banker, as many people believe. President Obama’s  stimulus package was bad policy, but the notion that China is now funding our economy as a result is a fallacy.

America could get by without China funding its debt. What’s largely unknown is that China officially holds less than 7 percent of U.S.  treasuries, and that Chinese bond purchases declined in 2009, to under $100 billion, while our deficit soared to an all-time high of $1.4 trillion.

Moreover, China does not buy our debt for our sake; it does so it because it depends on an economy as large and sound as ours for its own growth propelled through trade:  The same set of rules that keep its currency undervalued means, by law, it can’t spend at home the huge pile of cash that it sits on.

In that respect, China is more directly tied to us than we are to them. If the United States were to discontinue trade with China, it would hurt them more than us.

Finally, China is not going to surpass the United States as the world economic leader any time soon. We control about a fourth of the wealth in the world – more than China, India, Japan and the rest of Asia combined. Other indicators are just as definitive. The average American earns close to fifteen times more than the average person in China. If the  United States keeps tax rates low, shows spending discipline, and brings the deficit down to promote solid economic growth, there is strong reason to believe that China will never surpass the United States as the world’s largest economy.
