     China is still only eighty-ninth in the world in per capita GNP, and its Gini coefficient of economic inequality is higher than those of the two other countries to which it is often compared—the United States and India.

     In fact, France’s Gini coefficient, the measure of inequality in a society, is lower today than it was during les trente glorieuses (1945 to 1975), when postwar France regained confidence by helping to pioneer first Concorde, then the TGV, and then in the early 1980s the proto-internet (the Minitel).
