Somewhat slower growth in the near-term is a tradeoff worth making for higher future income. This is clearly good not only for China, but also the world economy. By 2030 China—especially with successful reforms—will almost certainly be the world’s largest economy. So China’s success—which will substantially increase income in China—will also mean much higher global demand and will thus be hugely important for a robust and healthy global economy.
Less growth in China today in exchange for more, much more, income in the future. So, less is indeed more.
