It's deeply wise for the Chinese to be pro-urban in terms of development. They're creating space for ideas and human capital to be developed.

One classic paper compared the effects of right-to-work laws on factory jobs in neighboring counties, on either side of a right-to-work border. It found that manufacturing grew 23.1% faster between 1947 and 1992 on the anti-union side of the divide.

There's a reason Atlanta, Dallas, Houston and Phoenix are our four fastest-growing areas. They offer an astonishingly high standard of living for ordinary Americans. New York City is a great place to be really rich and not a terrible place to be really poor, but it's a pretty hard place to live on $60,000 a year. You don't experience anywhere near the basic standard of living you would in Houston on the same income.
