Here you can found an interesting but older interview with W.Sachs on development. He argues:
Development has brought a new global middle class but the failure of 45 y of development is that it has produced a deep sense of inferiority in the South. Some other issues Sachs talks about like the birth of development in 1949 are mirrored in contemporary disscusions in the anthropology of development
