Interesting you haven’t mentioned the points I’ve made about the exploitation of the children but rather concentrated on the money.
I have read your post and in regard to the financial points you have responded to, I note with to (3), you carefully failed to mention the cost of the flights, vaccinations, insurance etc. A return flight from Dublin to Kolkata alone costs roughly €1000
You have said that of the €2500 you have mentioned, €2100 goes to the charity. You have not said how much of that €2100 then goes to administer these programmes, the cost of transporting the voluntourists / photogenic children around etc. I suspect you don’t know - it’s fairly common for that information to be well hidden.
So yes, I think the majority of the money does go fund the trip not to the charitable aims. Even if I’m wrong, what level of child abuse are you suggesting is acceptable in return for the cash? Because that’s what is happening even if you only look at the emotional exploitation the charity are admitting to. If you also take into account what is likely to happen when you facilitate access to vulnerable children with no DBS checks, in some cases the abuse is likely to be significantly worse.
As for 6, if there weren’t a constantly changing cast of voluntourists, activities with the children would have to be done by trained, qualified professionals. Who yes, would be paid for their work. So that is what’s happening, even if (again), the charity does their best to conceal that fact.
Children in the developing world are being used to make comparatively wealthy Western teenagers feel good about themselves in return for cash (much of which doesn’t benefit the children in question).
As a rule of thumb, if it wouldn’t be acceptable for untrained teenagers to be doing this in the UK / Ireland (and there’s no way it would be allowed), it’s not acceptable just because the children in question are in a country in the developing world.
