Long-term economists such as John Ikerd of the University of Missouri believe in applying "the Golden Rule across the generations doing for future generations as we would have them do for us." Professor Ikerd says: "The three cornerstones of sustainability are ecological soundness, economic viability, and social justice." He thinks that animal factories are deficient by all three measures.
