CITIES ARE ANTI-HUMAN:

FOR years Lin Chen resisted his wife's entreaties to move abroad. Then, when their daughter was born in 2012, he started thinking about her schooling. He realised he wanted a less stressful education than the one he and his wife endured in their climb to the middle classes, and he wanted to leave space for fun. "My wife and I suffered a lot," he says. "I don't want my daughter to suffer through all that."

And so the Lin family will soon be off to Adelaide, Australia, part of the greatest and most consequential wave of emigration in modern Chinese history: middle-class Chinese seeking not better opportunities or political freedoms but a better quality of life. Chinese emigrants are leaving good jobs, cashing out their high-priced homes (or investment properties) and leaving China's rat race behind. They are unlikely to find better jobs anywhere else, but the air and water are less polluted where they are going, the social safety-net less frayed and the food safer to eat. And there is no one-child policy.
