If this weren't a real problem - why are so few people trying to tackle actual problems that make millions of people miserable? Like health & sanitation in the third world. Or fixing the political process in the U.S. (and everywhere) so that people with less than a million dollars actually have a voice? Or matching up the millions of job seekers with the millions of jobs that go unfilled because there's nobody suitably skilled for them? Or finding a sustainable energy source so that we can maintain our lifestyle when the oil dries up?
