In case you missed Bill and Melinda Gates' 2014 end-of-year letter about global development, a few highlights:
The global picture of poverty has been completely redrawn in my lifetime. Per-person incomes in Turkey and Chile are where the United States level was in 1960. Malaysia is nearly there, as is Gabon. And that no-man’s-land between rich and poor countries has been filled in by China, India, Brazil, and others. Since 1960, China’s real income per person has gone up eightfold. India’s has quadrupled, Brazil’s has almost quintupled, and the small country of Botswana, with shrewd management of its mineral resources, has seen a thirty-fold increase. There is a class of nations in the middle that barely existed 50 years ago, and it includes more than half of the world’s population.
A prediction from the Gates':
By 2035, there will be almost no poor countries left in the world. (I mean by our current definition of poor.) Almost all countries will be what we now call lower-middle income or richer. Countries will learn from their most productive neighbors and benefit from innovations like new vaccines, better seeds, and the digital revolution. Their labor forces, buoyed by expanded education, will attract new investments.
A few countries will be held back by war, politics (North Korea, barring a big change there), or geography (landlocked nations in central Africa). And inequality will still be a problem: There will be poor people in every region.
But most of them will live in countries that are self-sufficient. Every nation in South America, Asia, and Central America (with the possible exception of Haiti), and most in coastal Africa, will have joined the ranks of today’s middle-income nations. More than 70 percent of countries will have a higher per-person income than China does today. Nearly 90 percent will have a higher income than India does today.
