The way I've explained this to people is that it's entirely possible in the US to rise to the top of your profession in any industry without ever moving to NY or LA, except maybe finance for NY and film/television for LA.[1] The equivalent is possible in Australia, Canada, and Germany, but impossible in the UK or France.

[1] And even here there are exceptions. For the entirety of the century that Hollywood has been "Hollywood", the creative types in LA have worked under control of the money men in NY. This is still true, except that the money men are now also in Dallas (AT&T), Philadelphia (Comcast), or Tokyo (Sony). In finance, one can become a managing director at a New York investment bank while always based in a regional office like Chicago, Atlanta, Dallas, or San Francisco (I think Byron Trott never left Chicago during his Goldman career).
