Yes but California is an example of very rich state per number of inhabitants of a vast county like US. For instance in Italy the distribution of richness is also very unevenly distributed, with a few of the north regions accounting for a vast amount of the whole richness. In this regions probably the richness per inhabitant is comparable to the one of California, or possibly even more. For instance the region of Lombardia alone has 248,119 million euros GDP, that is 25,251 per inhabitant.
