To me this is no news at all. There are prostitutes who make themselves available to foreigners in Haiti? That's hardly news - half the prostitutes in the DR come from Haiti. The girls who do this do so with the full knowledge of boyfriends, husbands and often families. The girls are not exploited, they are delighted to earn the money. There is terrible unemployment in Haiti and this is one way a girl can earn money to feed the inevitable children. And in the articles I have read, nowhere do I see that there is any evidence of underage girls being involved - just the word that it is a possibility. Hardly enough to call anyone guilty.
I remember talking with a Haitian friend about this practice - when the scandal of the UN troops and the underage boys broke years ago - and she said that most certainly there would be underage girls if the men wanted underage girls because the girls were so broke that they would do anything for money.
there is a prominent Dominican musician who promotes Haitian music and per a good friend of mine who knows him and knows the Haitians in the DR involved - also accepts "sexual favors" from young Haitian girls while "out of the road. He also pays the musicians sound $10 a day while publicly collecting awards for the promotion of Haitian culture. He used to live in my building. I told him once that I knew how much he paid the Haitian musicians in the field and did not want to talk to him any more.
There was a man who was contracted by a very big international NGO after the earthquake in Haiti. He took the opportunity to set up a date with a hooker. When he got to the designated assignation, he was kidnapped and held for ransom.
Sex tourism is a fact of life https://en.wikipedia.org/wiki/Sex_tourism
There are countries - such as Costa Rica - where the sex workers are protected by the government, given safe working environments, regular health check ups, retirement benefits, police protection.
I suppose that it is up to every participant to decide if s/he is engaged in exploitation or fair commerce when exchanging sex for money.
But - I do find it a bit odd that it seems that so few here would "get it" that it is inappropriate for an aid worker to engage in the practice... but then again - I did not understand that so many men agreed that Bill Clinton had NOT indeed had sex with that woman.
Two universes that evidently very rarely intersect.
