It’s not about the quality of education. The educational institutes post date the industry cluster. Paris was a centre of fashion before fashion was studied in universities, ditto Nee York. Los Angeles was the place for movies in the states for three or four decades before film schools existed. New York was the home of American finance long before commerce or finance were more university centred than apprenticeship, if that’s even true now. Agglomeration economies of expertise lead to large, deep labour markets. I doubt California is much behind Boston in biotech research but the industry is all in the BosWash corridor, mostly near Boston.
