Proponents of free trade would argue that trade allows people in two countries to concentrate on producing what each does best. A highly skilled worker in a rich country could now oversee designing a product and hires another highly skilled one in a poor country to supervise the production process. In this framework, the highly skilled get richer, while the lower skilled stay out of the loop. As per calculations by the World Bank, the Gini index (which measures income inequality) has declined since the country integrated into the global supply chain. It is only a matter of time before robots (or artificial intelligence)-- highly skilled workers available in infinite numbers -- join this competitive labour market.
