One advantage China has over the US is that the Chinese government does not waste money on a hyper-interventionist foreign policy. The United States government spent approximately $752 billion on the military in fiscal year 2013. In contrast, China spent approximately $188 billion. While China may be increasing its military spending, it has a long way to go to catch up to the United States.
It is difficult to see how the American people, other than those who run or work for the military-industrial complex, benefit from this spending. Military spending, like all government spending, hampers private sector growth by taking resources away from investors, entrepreneurs, and consumers while contributing significantly to the national debt. In contrast, a return to the policy of peace and free trade would allow those resources to be used by entrepreneurs to create new businesses and new jobs.
News that China is soon to surpass the United States as the largest economy in the world is a stark reminder of how the American people are harmed by the welfare-warfare state, crony capitalism, and fiat currency. The only way to avoid continuing collapse is to finally reject an interventionist foreign policy, stop bailing out and subsidizing politically powerful industries, and restore a free market in money.
