I am not sure I go for the want vs need when others are dying argument too much.
Well...it wasn't an "argument" at all, and pretty far from the point you seem to think was being made. You can live forever without a cellphone; you'll be dead in three days without water. If you're trying to prepare for the future, do you invest in iPhones or do you try to ensure that you'll have water?
It's a choice. There may be a "right" answer, but only time will tell what that is. Me, I'm struck by how many people in this thread seem perturbed by others having a different take on the question.
