Evan Selinger, Kevin Outterson and Kyle Powys Whyte published a paper last month titled “poverty tourism, justice and policy” in which they discuss whether poverty tourism should be subject to specific policy constraints based on moral grounds.
They look at this matter through favela tours in Rocinha, Brazil and garbage dump tours in Mazatlan, Mexico. In their conclusion they argue that slum or poverty tours are a result of complex social relationships that require individual attention and policy research.
