We are quickly reaching the point on HN that we are becoming a parody of ourselves. What is this tripe? Why are we consuming it so greedily?
Look, the poor in America today are tremendously better off than before. And yes, I find it interesting as a hacker to observe statistical data, I also know enough to know that methodology and meaning count for a hell of a lot here. It's one thing to note relative percentage differences in relative quintile rankings. It's quite another to end your article with this over-the-top emoting.
Come now, is it not obvious that the quintiles area completely different now than, say, 40 years ago? Is it not obvious that things like public transportation are probably meaningless when applied to a geographic area this size? How about the fact that the people in, say, rural Florida in 1980 are probably not the same ones that would be there in 2010? Does migration between states play a role? Illegal immigration? Do poor people self-select certain areas? More provocatively, what's the actual movement compared to the movement desired?
I love statistics, but far too often we try to beat meaning out of aggregate information that just isn't there. Then we bandy around whatever meaning we've drudged up to support our pet theories. One of the reasons I love startups so much is that to address a market you take statistical data and then test it. That's what we're missing here. We have a lot of hand-waving, correlation, generalizing, and blame. Not so much with the reproducible testable hypotheses. A little more of that and a little less soft, squishy social sciences, please. Otherwise this place is going to start looking like a meeting of the royal astrologers: lots of posturing and invective but very little of value.
You guys are consuming this great fluffy social sciences mish-mash and treating it as if it were the same as recent results on the mass of the Higgs-Boson. They're different categories of information. All science is provisional, but the soft sciences are the most provisional of all. Bears remembering.
