Why Are America’s Most Innovative Companies Still Stuck in 1950s Suburbia?

It comes across to me as too much "duckspeak", that is, there is more to the suburbs than just "keep white" and "crush labor", even though these are factors. For example, black people moved to the early suburbs because they found life there attractive, and then there was white flight against as a result of that.

Looking at America is 2016 it is important to separate out "innovation" from various forms of real and alleged "rent seeking" and ask questions such as:

-- are Los Angeles, San Francisco, and New York successful because they are successful or because they can control the dialog and make people think they are successful? -- does an overconcentration of cultural production in major urban areas have harmful effects on the culture; simply speaking commercially, can they get in to the heads of "flyover state" people enough to be able to sell them goods and services? -- could overconcentation of cultural production have something to do with the "Future Shock" rage behind Don Trump and Bernie Sanders? Since we've outsourced our dreams to Hollywood, for instance, people feel that their own personal stories are erased.
