The Great Divide in the Global Village
Why has the developing world become poorer as the industrialized nations have grown richer? Robust growth depends on a strong state that can enforce laws, yet many impoverished countries lack effective governance. And by strictly limiting immigration, rich countries deny the world's poor a chance to vote with their feet.

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.

After being shackled by the government for decades, India's economy has become one of the world's strongest. The country's unique development model -- relying on domestic consumption and high-tech services -- has brought a quarter century of record growth despite an incompetent and heavy-handed state. But for that growth to continue, the state must start modernizing along with Indian society.
In a major new work, Benjamin Friedman presents a compelling moral case for growth-oriented economic policies. But even he sometimes needs reminding that the kind of growth matters as much as the amount.
Paul Collier offers strong recommendations for helping "the bottom billion" -- those living in poor countries caught in growth traps. But he cannot overcome a basic problem: how to create growth where no functioning economy exists.
