The US wins economically as the Chinese middle-class grows. What products do you think they will buy when their wages increase - a knock-off phone in Hong Kong or the iPhone 5 or 6?

The market for American goods increases as the Chinese middle class grows. Chinese consumers don't prefer cheap knockoffs, they buy them because they can't afford the most expensive genuine article. Look at the Chinese market for luxury cars as an example of what will happen with increasing speed: http://magazine.wsj.com/features/the-state-of-luxury/cars/

Granted, US car makers aren't in great shape right now, but other industries can take advantage of the Chinese appetite for luxury consumer goods (electronics, cosmetics etc). The elecronics may be manufactured in China, but the profit margins are mainly with the US companies who designed and developed them.

Savvy US companies can sell their goods in increasing volume due to the larger overall global market. Many US multinationals make large chunks of their profit overseas, yet you don't hear people saying the US should enter into trade wars with South America, Europe or Australia.
