Sociologists could have a field day with this question, but the explanation could be something as simple as the fact that people who live in cities are relatively insulated from how difficult and challenging it can be to produce the food, energy, equipment, devices, etc., that comprise the affluence that urbanites enjoy. In their urban cocoons, city-dwellers take for granted the abundance and availability of the economic goods that they consume. For instance, many well-to-do, educated urbanites see no downside to supporting stricter regulations and higher taxes on energy producers, because to them, energy is something that is always there at the flip of a switch (except during the occasional hurricane, as some New Yorkers recently discovered). Life in the city for affluent Americans creates the illusion that all they have to do is demand something and—presto!—it will be there when they want it.
