Africa aid is a fantastic example of these consequences. The west have gradually realised over time that giving aid to these impoverished countries has far too often substandard effects to the long term health of the local communities. The aid creates dependancy, it breeds corrupt african polititians/war-lords who funnel-up all the aid money,. In summary something you'd think "Yep, definitely moral and righteous!" can do damage, even if I believe effective aid to africa is a thing we should do (but i believe a lot of the aid systems in place presently are utterly shambolic).
Give a man a fish and all that...
In the end politics and people are always more complicated than you think, more than I, you, or a little quipy saying could grok. So deriding and shouting at people (like you blatantly did to the parent comment, which was somewhat insightful and not low quality) who maybe just try and look at things from different angles, be the "Tenth Man" so to speak, isn't going to solve absolutely anything, and more relavently is not something you should be doing on HN, at all.
