Aid is institutionalised - and bureaucratised. Critics to the right of the political spectrum in the US do not like that. They argue that welfare programmes do not work in their own country and should therefore be cut. Look at those hooked on drugs, they argue. They are addicted and lose their individuality.
Aid does the same, but on a collective level.
Let the poor fight for themselves, but don't get them hooked. An argument, by the way, that could have been heard in radical leftist circles in the sixties. Conservatives in Europe were somewhat slow in the learning, but they picked up the word from Washington. Gradually the notion of 'aiddependency' was coined and became acceptable currency in aid agencies. It gave a moral basis for discontinuing aid programmes when the donors saw fit to do so.
