That's a great point, and I agree: the subway doesn't do a uniformly good job of serving the city's population. There's a reason the wealthy areas are around the lines that they're around.

The claim (which I agree with!) that the subway experience is worse when poor doesn't have the temporal aspect that your original claim did (that subway performance has gotten worse recently.)
