You raise a good point. If something is a ‘human right’ does that mean it should be free? Ultimately, someone has to pay and the question is ‘who is best placed to pay’ for an item like a personal latrine?
I am personally of the opinion that sharing the expertise of the poor (so that we can learn from their experience) is already changing the narrative ... as it does not objectify what they lack and what they need from us. This sharing of local expertise enables local proponents to learn from each to replicate and inform policy change, which is something that is already being supported in Bangladesh through the Horizontal Learning Program (see www.horizontallearning.net). Please take a look and feel free to contact me or any of the various partners to learn more about it.
