We hate this question, but we unfortunately get asked it sometimes so here goes. First, when we say one billion kids are underserved in education, that includes a range of kids – from kids in Brazilian favelas to underfunded classrooms in Nairobi to rundown communities in Mississippi. The caricature that they're all only starving kids with flies on their faces awaiting handouts is not only wrong, it's also slightly offensive.
Second, none of the world's problems (ranging from climate change to human rights) can be solved in one fell swoop. But by investing in the education of the future of humanity, we increase the chances that tomorrow's adults have the tools to solve those problems effectively.
