The ‘Epilogue’ compares the lives of the rich and poor through the lens of economics. Similar people can have very different lives based on the communities they inhabit. Members of less developed countries face ‘problems’, whereas people in the developed world face ‘challenges’. Economics provides a unified way of looking at their lives. Success and failure are about more than effort and luck, they also rely on social factors. Listing the things that the developing world needs is of limited use. The goal needs to be the promotion in these societies of the institutions, policies, and civic attitudes needed to increase inclusive wealth.
