I have no doubt there are some in Oxfam and elsewhere who exploited people into prostitutes: all power corrupts, don't you know. However, I see little evidence it is widespread yet, nor anything to make references to the orgies of Caligula appropriate.

More oversight? Yes, of workers in the field ny the organisation. Oversight of the organisation by child protection and similar specialists? Again, yes. But by people who were calling for foreign aid to be cut before this surfaced? I don't think so.
