Wealth and Rails: Economic inequality, station by station

I don’t really see the relevance of the subway lines in the story – the story is just saying that there are areas of high income and areas of low income. Doh!

Any city has that regardless of whether there are subway lines or not (often historically determined by the direction of the prevailing winds so industrial smoke and dust blow away from the higher priced areas).

In fact, high income areas may resist subway lines for the riff raff and crime they may bring in, and likewise, as a social service, rapid transit may target lower income areas more likely to use its services – creating internal biases to using subway lines as a gauge.
