Enrico Moretti's groundbreaking research shows that you don't have to be a scientist or an engineer to thrive in one of the brain hubs. Carpenters, taxi-drivers, teachers, nurses, and other local service jobs are created at a ratio of five-to-one in the brain hubs, raising salaries and standard of living for all. Dealing with this split-supporting growth in the hubs while arresting the decline elsewhere-is the challenge of the century, and The New Geography of Jobs lights the way.
