But someone living on Long Island lives in an area where pay is higher than other areas of the country where cost of living is lower. You can see that in this thread talking about police and medic pay levels. You see it in threads here that come up about teacher pay.
Yes but someone that is barely middle class where I live looks fairly poor against country averages and gets college assistance. Someone that is barely middle class on long island looks like they make alot compared to country averages and does not.
Off topic a bit but...
I have found two main differences in having a high salary in high cost of living area vs low salary in low cost of living: One is taxes and government aid as described here, the other is travel (because besides the flight going to disneyworld costs the same for the same product no matter where you live, and higher cost of living areas tend to have more flight options and more direct flights to sometimes actually have cheaper airfare)
