INCOMES ARE DIVERGING
Mainstream economic thought promises that globalization will lead to a widespread improvement in average incomes. Firms will reap increased economies of scale in a larger market, and incomes will converge as poor countries grow more rapidly than rich ones. In this "win-win" perspective, the importance of nation-states fades as the "global village" grows and market integration and prosperity take hold.
But the evidence paints a different picture. Average incomes have indeed been growing, but so has the income gap between rich and poor countries. Both trends have been evident for more than 200 years, but improved global communications have led to an increased awareness among the poor of income inequalities and heightened the pressure to emigrate to richer countries. In response, the industrialized nations have erected higher barriers against immigration, making the world economy seem more like a gated community than a global village. And although international markets for goods and capital have opened up since World War II and multilateral organizations now articulate rules and monitor the world economy, economic inequality among countries continues to increase. Some two billion people earn less than $2 per day.
At first glance, there are two causes of this divergence between economic theory and reality. First, the rich countries insist on barriers to immigration and agricultural imports. Second, most poor nations have been unable to attract much foreign capital due to their own government failings. These two issues are fundamentally linked: by forcing poor people to remain in badly governed states, immigration barriers deny those most in need the opportunity to "move up" by "moving out." In turn, that immobility eliminates a potential source of pressure on ineffective governments, thus facilitating their survival.
Since the rich countries are unlikely to lower their agricultural and immigration barriers significantly, they must recognize that politics is a key cause of economic inequality. And since most developing countries receive little foreign investment, the wealthy nations must also acknowledge that the "Washington consensus," which assumes that free markets
