CITIES WERE A MISTAKE:

AROUND THE WORLD, THE TIDE IS TURNING AGAINST MEGACITIES (Joel Kotkin 01/18/2016, New Geography)

The massive construction waste collapse last month in Shenzhen reflects a wider phenomenon: the waning of the megacity era. Shenzhen became a megacity (population over 10 million) faster than any other in history, epitomizing the massive movement of Chinese to cities over the past four decades. Now it appears more like a testament to extravagant delusion.

In 1979, Shenzhen was a small fishing town of roughly 30,000 people when it became a focus of former Chinese leader Deng Xiaoping's first wave of modernization policies. Now it is a metropolis of 12 million whose population grew 56 percent between 2000 and 2014. For years, it stood as the brash wunderkind of Chinese cities, proud of its gleaming infrastructure that is now increasingly suspect.

The Shenzhen collapse came four months after a similar deadly public safety disaster in Tianjin, another relatively new megacity, where an explosion at a chemical warehouse killed 173 people. And of course, there is the widespread urban air pollution that is hazardous in Beijing and simply noxious elsewhere. Simply put, the once compelling "economies of scale" offered by increasing the size of cities have broken down in urban agglomerations over 10 million people, where their size has now become encumbrances to further growth, not to mention the happiness and health of their citizens.
