I would probably start with a thesis statement of some sort (I'm getting a bit tired now, so bear with me if this isn't the clearest example):
"Wealthy nations should give no aid to poorer nations until those nations take steps to help themselves."
Then, I would probably summarize a couple of reasons why I believe the thesis to be true
"Food aid and economic support to developing nations only aggravates those nations' social and economic problems in the long term by allowing them to delay the systematic reforms needed to be able to function properly on their own."
"Worse, such aid not only allows governments to delay necessary reforms, it also, to the extent that it is successful at all, begets only an ever greater need for aid in those countries."
Notice how each reason in the summary could be paraphrased and used as a topic sentence for a body paragraph. That is in fact how I would begin my body paragraphs, elaborating on my reasons and giving specific examples to support my points.
