Its one of those us or them situations. Either you take them and already risk overcrowding your country, or you help yourselves while they die. Personally I don't see why we can't just invest into modernizing 3rd world nations. I'd gadly pick up a hammer and start building houses, teaching them the ways of irrigation, advanced farming. How to filter water. Lane down pipes for running water and sewage. Also try to find ways to create industry to support those luxuries. Its a lot better than throwing money at something and watch as your charity money goes to a cause that does nothing.
