I'm sorry, but there's no way for Bill Gates to say that without sounding like an arrogant asshole. The world doesn't have to unite and spend all of its income on what Bill Gates says is the most important priority. There are at least other 100 priorities that could be put above malaria, and even those shouldn't be done exclusively.
I've always found this a puzzling argument. He wants to spend his billions on malaria and polio, should we let him do that or should we start a committee that decides how best he should spend his money? Maybe he can do a televised competition where people go on stage and make a 1 minute pitch for him to choose one cause over another. Or maybe he can just keep doing what he's doing and solve two really big problems and then move on to something else that he wants to do when that's done.
He didn't suggest that people pour money into malaria either, really, he just suggested that they don't pour it into connectivity, and he had a really good point. But if people want to do that, then maybe we can solve malaria and polio AND get people connected at the same time!
Name them. What 100 are those? Malaria is one of the single biggest factors in the development of the average African child's life, and the effects of it resonate through a lifetime. It is almost certainly the most Important priority, rather than some photo sharing startup that is "Dropbox meets Quora for Snapchat users". Clearly, no one has to go do what Gates is saying, but the hyperbole here is silly.
