--- - |2 Abstract An essential part of Pope Francis’s critique of the “economy of exclusion” is the concept of the “throwaway culture,” which is an attitude and a reality that goes beyond mere exclusion. Francis is building on critiques of consumerism (what John Paul II called “economism”) that noted both the environmental impacts of unnecessary waste and the social and human impact of reducing humans to mere consumers—the idea that happiness is shopping. Francis adds to this a concern for the people on the margins of society who are treated as disposable and for the consequences of climate change, both of which are connected to the throwaway attitude. This article looks at Francis’s views within the tradition of Catholic social thought and at how economists, especially Adam Smith, who provided the foundation for modern economics, looked at waste and consumerism. - 'American Journal of Economics and Sociology, Volume 78, Issue 4, Page 973-1008, September 2019.
