It's funny how there's a tension in the writing - that while the author points out how there has been radical change, he also attempts to point out all the problems to be overcome - some which are based on values he pushes himself. That said, there is a remarkable story coming out of Africa - it's because of markets and capitalism that the world needs more of, not less.

Some critics point to inequality over economic growth / equality of opportunity - but that's a value choice between whether it is more important to be equally poor or wealthier at all segments of the population... and it would seem some developing countries are beginning to get it.

Yet at that same moment when leading development thinkers saw the most modest of futures for the sub-Saharan as a region, a diverse group of determined African technocrats -- from Ghana to Uganda, Zambia to Kenya, South Africa to Rwanda -- joined forces with technologically savvy, globally oriented capitalists to launch a quiet revolution in development thinking. In time, their changes helped lead to Africa's dramatically improved economic performance, and greater confidence in their ideas.

The economic evidence that they were right, building since the start of the new century, now seems incontrovertible. In the ten years from 2000 to 2010, six of the world's ten fastest-growing countries were in sub-Saharan Africa: Angola, Nigeria, Ethiopia, Chad, Mozambique, and Rwanda. In eight of the past ten years, sub-Saharan Africa has grown faster than Asia, according to The Economist. In 2012, the International Monetary Fund expects Africa to grow at a rate of 6%, about the same as Asia.
