I wonder if sociology has anything to say on this topic. My sense is that young tech workers flocking to coastal cities are voluntarily extending their adolescent years, in the same manner as many graduate students. For many young people, 10 years working in Silicon Valley is really a form of graduate school, equivalent in earning potential to a Ph.D. at a world-class university. The big question: after you get your tech "graduate education", are you able to put down roots and create an adult life in these places, or does it make sense to move elsewhere?
