Lots of factors helped to develop America’s west coast. Certainly the pioneer spirit that initially brought settlers west led to a strong sense of individualism and entrepreneurism that pushed development forward. The allure of the weather brought many transplants west. But I think the West Coast benefitted much more from the kinds of connections identified by Jim Russell at Burgh Diaspora (and now at Pacific Standard) – the West Coast had an effective talent attraction strategy, created strong bonds with the East Coast, and never let them go. It’s a lesson that the shrinking cities of the Rust Belt should heed and practice.
I’m no historian, nor am I the ultimate authority on the development of cities. But it’s clear West Coast cities did some things that Rust Belt cities did not. As we all know, the settlement of California was kicked off with the Gold Rush of 1849. Prior to that California was a sparsely-settled former Mexican territory with no physical or institutional infrastructure. The Gold Rush propelled Eastern financiers to provide the money to develop San Francisco as the financial center that would open up the west, and give it the physical and institutional resources to deliver its goods to the rest of the nation. San Francisco never relinquished those ties.
Further south, Los Angeles used its fabulous and consistent weather as a means to attract parts of a budding film industry previously based on the East Coast. The growth of the film industry ultimately led to the growth of the media industry in Southern California, and voila – the economic underpinnings of a major metropolis are established. Like San Francisco, LA never relinquished those ties. (Side note: I don’t think you can understate the importance of the Rose Bowl in luring Midwesterners in particular to Southern California. The “Granddaddy of Them All”, started in 1902, annually brought the Big Ten’s best and brightest for a few weeks of sun and fun in winter. The strategy paid off.)
The lesson here for the Rust Belt is talent attraction, and maintaining the connections over time. San Francisco was able to parlay its Eastern financial connections into the development of a strong financial center, which later served as the financial apparatus for the tech industry. Los Angeles was able to do the same with the film industry and media, and it could be argued that the city’s ties to Midwestern interests led to the growth of the defense industry there.
