I'm in the middle of writing a thesis on tourists negotiating confrontations

I'm in the middle of writing a thesis on tourists negotiating confrontations with poverty while on holiday in third world countries. It is easy to see that these confrontations touch on ethics and justice as the tourists are (relatively) rich, their hosts are poor and tourism is about enjoying luxuries (hedonism) while around the 'tourist bubbles' people are struggling. Considering this I focus on how tourists 'legitimise themselves', using discourse analysis (which discursive techniques do tourists employ) following Foucault on power and truth within constructivism, making sidesteps to Baumann (exclusion), Stanley Cohen (states of denial) and Zizek (cultural capitalism). Do you have any more ideas on how I could elaborate on these issues using philosophy? Please point me in the right direction of interesting (modern, postmodern, critical) philosophies!
