However economics is not a zero sum game. I'm not adversely affected if Asia's economies grow. In fact, I'd love to see them succeed. More wealth anywhere is good for free people everywhere; it give's me more people to trade with.
You've completely forgotten about automation. Within a generation robotics will make low cost labor obsolete. We won't need factories of Chinese workers to build our products; We'll have factories full of robots.
Also, I don't really care who has the most power. I don't care if America has the largest military in the world. I only want our military to protect our borders and police shipping lanes.
If China becomes more powerful than the west and my standard of living increases thanks to technology, I don't care. The only thing to worry about is chinese military intervention, but even if they have a significantly more powerful military our nuclear deterrents will prevent them from directly harming us.
