Is the brandt line valid

The Brandt Line was a theoretical demarcation line proposed by ex-German Chancellor Willy Brandt and others in the 1970's and 1980's. It was designed to show how Southern Hemisphere economies were less affluent overall than those in the Northern Hemisphere.

The line highlighted the lack of industrial development in South America and Africa, partly due to their Demographics and partly to their exploitation as colonies by Europe's countries from the 16th through 19th centuries. Brandt and others urged increased aid by developed nations to social and economic programs in the "Third World" nations.

The Brandt Line is also known as the "North-South divide".
