the increase of income per-capita. Kuznets had two similar explanations for this historical phenomenon: workers migrated from agriculture to industry; and rural workers moved to urban jobs. In both explanations, inequality will decrease after 50% of the shift force switches over to the higher paying sector. Evidence Inequality has risen in most developed countries since the 1960s, so that graphs of inequality over time no longer display a Kuznets curve. Piketty has argued that the decline in inequality over the first half of the 20th century was a once-off effect due to the destruction of large concentrations of wealth by war and economic depression. The Kuznets curve and development economics Critics of the Kuznets curve theory argue that its U-shape comes not from progression in the development of individual countries, but rather from historical differences between countries. For instance, many of the middle income countries used in Kuznets' data set were in Latin America, a region with historically high levels of inequality. When controlling for this variable, the U-shape of the curve tends to disappear (e.g. Deininger and Squire, 1998). Regarding the empirical evidence, based on large panels of countries or time series approaches, Fields (2001) considers the Kuznets hypothesis refuted. The East Asian miracle (EAM) has been used to criticize the validity of the Kuznets curve theory. The rapid economic growth of eight East Asian countries—Japan; the Four Asian Tigers South Korea, Taiwan, Singapore, Hong Kong; Indonesia, Thailand, and Malaysia—between 1965 and 1990, was called the East Asian miracle. The EAM defies the Kuznets curve, which insists growth produces inequality, and that inequality is a necessity for overall growth. Manufacturing and export grew quickly and powerfully. Yet, contrary to Kuznets' historical examples, the EAM saw continual increases in life expectancy and decreasing rates of severe poverty. Scholars have sought to understand how the EAM saw the benefits of rapid economic growth distributed broadly among the population. Joseph Stiglitz explains this by the immediate re-investment of initial benefits into land reform (increasing rural productivity, income, and savings), universal education (providing greater equality and what Stiglitz calls an "intellectual infrastructure" for productivity), and industrial policies that distributed income more equally through high and increasing wages and limited the price increases of commodities. These factors increased the average citizen's ability to consume and invest within the economy, further contributing to economic growth. Stiglitz highlights that the high rates of growth provided the
