A philosophy journal article! The abstract:
Is it morally permissible for financially privileged tourists to visit places for the purpose of experiencing where poor people live, work, and play?
…First, even mutually beneficial transactions between tourists and residents in poverty tourism always run a risk of being exploitative.
Second, there is little opportunity to determine whether a given tour is exploitative since tourists lack good access to the residents’ perspectives.
Third, if a case of poverty tourism is exploitative, it is so in an indulgent way; tourists are not compelled to exploit the residents.
In light of these considerations, we conclude that would-be tourists should participate in poverty tours only if there is a well-established collaborative and consensual process in place.
Seems reasonable. I have probably said all I have to say on the subject. My previous takes here.
