Global poverty has received significant attention in the past decade, particularly after the adoption of the United Nation's Millennium Development Goals in 2002. Commentators and ethicists like Peter Singer have long held that the wealthy of the world have an obligation to help the poor. While the sentiments may be positive, there are real harms that have come from this kind of top down thinking. Subsidiarity, to the contrary, is a much more realistic and morally tenable approach to global poverty.
