Erich Fromm's "Escape from freedom". It is very well written and the subject matter is truly mind-bending: how can an educated people decide to throw their freedom away and give power to a dictator? E. Fromm was German psychologist, and jewish. He fled to America in the 1930s. He writes with a composite point of view, at the intersection of psychology, sociology, and philosophy, without getting stuck in a narrow analysis, and I think this is what makes this books and others by him so good.
