Peter Singer is an Australian philosopher that inspired Living High and Letting Die.
 Inspired by Peter Singer's 1971 essay "Famine, Affluence, and Morality," Unger argues that for people in the developed world to live morally, they are morally obliged to make sacrifices to help mitigate human suffering and premature death in the third world, and further that it is acceptable (and morally right) to lie, cheat, and steal to mitigate suffering. 
Peter Albert David Singer, AC (born 6 July 1946) is an Australian moral philosopher.
