Humble wheel spins its cycle of economic magic in China

Some still believe the wheel is man's greatest invention (never mind big data, artificial intelligence, supercomputers, superconductors and nanotech).

Arguably, the wheel is also one of China's best kept economic secrets.

I should know. I come from India, a comparable nation (population: 1.35 billion vs 1.41 billion) that's struggling to match China's economic heft (2017 GDP: $2.60 trillion vs $12.23 trillion) even as it celebrates its 72nd Independence Day on Wednesday. That struggle can be ascribed to India's inability to master the wheel like China.
