UNICEF, useless?

Somebody from UNICEF asked med today if I wanted to contribute a certain amount of money each month. I replied: "I am against overpopulation," with the Unicefer looking absolutely gobsmacked. She asked me if I thought if it was all right to which I repllied that I was the embodiment of evil. (I was, of course, being slightly ironic).

Anyways, that was just a point of reference. Do you think it is pointless to support those organisations? I think that if any support to "poor" countries is to help, it has to be put together as to optimize the effect. You can use this metaphor: if you are too make a wall collapse only with water at hand, you won't make it fall by scattering drops at it randomly - all those small water drops should be collected in a big bucket and then thrown at the wall, with the greater momentum leaving a greater effect. The end of poverty is a politically global job, not directly in the hands of the individual - who can, in the most cases, only help out effectively by supporting governmental efforts.
