For the past several decades, the conventional - and, until recently, the predominant - perspective on development in the international donor community has been that countries are poor because they lack resources, infrastructure, education, and opportunity. By this logic, if rich countries could only transfer enough resources and technology, improve human capacity enough, and support health and education enough, development would occur. To be sure, greater public resources, better physical infrastructure, and stronger public health and education are essential for development. But they are not enough, and they are not most crucial factor.
