This is a person that has helped move the animal rights agenda into mainstream. He did that using ethical arguments and demonstrating that we are not acting in a coherent or ethical way in relation to (other) animals. So he has been a thought leader that challenges systems even though it looks impossible.
When it comes to how we should look at the poor people of our own species he adopt a much more narrow perspective and by trying to be “pragmatic” he ends up writing a book that probably is meant to get him and others invited to rich people that want to provide philanthropic contributions to poverty.
Personally I also feel that the whole philanthropic approach feels a bit outdated. It is nice with philanthropy, but the big question today is how we can get business people using their core skills and delivering solutions that helps the poor. Even if not everyone can be Muhammad Yunus all companies should look how they can assess their contribution to poverty reduction (I wrote an article in China Daily about this two weeks ago).
