"The process by which money is taken from poor people in rich countries and given to rich people in poor countries".
Yeh, call me a cynic, but I believe more and more that it's so, so true.
Well, that's one aspect of it, namely the diverting of funds to improper uses and the corruption that both gives rise to it, and feeds off it. Mobutu, who was president of Zaire, had a fortune estimated to be $5 billion - though "only" a few million of these were ever tracked down, so perhaps there was some exaggeration.
What's worse, though, is the way aid destroys local economies.

However, the response of the West is to ship in food and distribute it for free. We've all seen the kids scrabbling for it - distressing, but at the same time gratifying. Except we don't think of what that dumping of free food does for the local economy. Anyone with a small surplus to sell is wiped out. Anyone thinking of taking the risk / expense of planting and harvesting food stops, because there is no point.
OK, we have the vagaries of the weather to deal with, war and all that. I accept that the picture is complex, but I deny that it is complicated. You have only to ask which countries are complete basket cases, and which received most foreign aid to see a correlation.
Make sure you understand causation first. For example, it does not rain so that plants can grow; plants grow because it rains. I suggest we start thinking about aid the same way. Do we provide aid because countries are poor? Or are countries poor because we provide aid?
Postscript:
After I wrote this I came across an item where the international aid group, Care, is getting concerned about the same thing, here.
