To be fair, many foreigners come to the slums wanting to understand poverty, and they leave with what they believe is a better grasp of our desperately poor conditions. The expectation, among the visitors and the tour organizers, is that the experience may lead the tourists to action once they get home.

But it’s just as likely that a tour will come to nothing. After all, looking at conditions like those in Kibera is overwhelming, and I imagine many visitors think that merely bearing witness to such poverty is enough.

Nor do the visitors really interact with us. Aside from the occasional comment, there is no dialogue established, no conversation begun. Slum tourism is a one-way street: They get photos; we lose a piece of our dignity.
