China’s population has seen some of the greatest improvements in human welfare in history during the past 50 years, including the near elimination of extreme poverty. Comparing this to slavery in the American South is frankly silly. It is like making light of slavery.
Economic development isn’t so easy, or more countries would already be rich. Look at peer countries: in 1970, China had around the same GDP per capita as India and lower than Indonesia, now it’s about 50% higher than Indonesia and 170% higher than India. If you view this through the institutions lens (which is the whole point of Robinson’s work), it’s hard to avoid concluding that China’s institutions aren’t particularly extractive, compared to nominally democratic countries at the same stage of development.
Whether this will continue to be the case is an open question. The doomer case for China is pretty fashionable, but again it’s useful to do a comparison. Look at the middle income countries and ask which ones can make it out of the middle income trap, and transition into an advanced economy. China stands a much better chance than almost any other middle income country, just from the fact that it’s already at the technology frontier in many industries.
