Are China’s leaders destined to ask each other, “Who lost Hong Kong?” It’s a question worth pondering after a holiday week that offered a stark reminder of just how restless -- if not unhappy -- a sizable percentage of the former colony’s residents are under Chinese rule, 17 years after the end of British sovereignty. Of course, nobody seriously entertains the idea of a political schism between Hong Kong and China.

For the second year in a row, Colombia has topped the list as the world’s happiest country, according to a survey released Thursday by WIN-Gallup. The survey known as the 2014 Barometer of Happiness and Hope reported that of the 1,012 Colombians polled, 86% self-reported as “happy,” while only 2% reported themselves as “unhappy.” This represents a rise of 9% from 2012 when 77% of respondents rated themselves as “happy.”

Have I been wrong all along? Some critics suggest my newspaper columns since 1995 on the politics and economics of the Mainland have been — oh — overly sympathetic toward China. I just don’t know. But no one can afford to be complacent. And so the worry popped up again, for several reasons.

China is preparing to surpass the United States as the world’s largest economy, in purchasing power parity terms. Already its economy is 80% the size of ours, and if current growth rate differentials persist, it will take China only about four more years to surpass us. At market exchange rates, China’s GDP is smaller, and is expected to remain less than ours until 2028. This is hardly surprising.

The Third Plenary Session of the 18th Central Committee of the Chinese Communist Party (CCP) closed mid-November, but it still keeps China-watchers awake. Foreign analysts were rather underwhelmed by the immediate outcomes: a bland, boilerplate communique issued on November 12.

"America is a large, friendly dog in a very small room," observed British historian Arnold J. Toynbee. "Every time it wags its tail, it knocks over a chair." And Spanish poet Federico Garcia Lorca said, "The only things that the United States has given to the world are skyscrapers, jazz, and cocktails." Opinions of America are like bellybuttons — everybody's got one.
