Rx for Global Poverty

What's the world's greatest moral challenge, as judged by its capacity to inflict human tragedy? It is not, I think, global warming, whose effects -- if they become as grim as predicted -- will occur over many years and provide societies time to adapt. A case can be made for preventing nuclear proliferation, which threatens untold deaths and a collapse of the world economy. But the most urgent present moral challenge, I submit, is the most obvious: global poverty.

There are roughly 6 billion people on the planet; in 2004, perhaps 2.5 billion survived on $2 a day or less, says the World Bank. By 2050, the world may have 3 billion more people; many will be similarly impoverished. What's baffling and frustrating about extreme poverty is that much of the world has eliminated it. In 1800, almost everyone was desperately poor. But the developed world has essentially abolished starvation, homelessness and material deprivation.

The solution to being poor is getting rich. It's economic growth. We know this. The mystery is why all societies have not adopted the obvious remedies. Just recently, the 21-member Commission on Growth and Development -- including two Nobel-prize winning economists, former prime ministers of South Korea and Peru, and a former president of Mexico -- examined the puzzle.

Since 1950, the panel found, 13 economies have grown at an average annual rate of 7 percent for at least 25 years. These were: Botswana, Brazil, China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, Malta, Oman, Singapore, Taiwan and Thailand. Some gains are astonishing. From 1960 to 2005, per capita income in South Korea rose from $1,100 to $13,200. Other societies started from such low levels that even rapid economic growth, combined with larger populations, left sizable poverty. In 2005, Indonesia's per capita income averaged just $900, up from $200 in 1966.

Still, all these economies had advanced substantially. The panel identified five common elements of success:

· Openness to global trade and, usually, an eagerness to attract foreign investment.

· Political stability and "capable" governments "committed" to economic growth, though not necessarily democracy (China, South Korea and Indonesia all grew with authoritarian regimes).

· High rates of saving and investment, usually at least 25 percent of national income.
