Is there seriously somebody out there in blogland who thinks it's "a great testament to economic progess that, walking round the city center these days, say, it's very hard to differentiate the rich and the poor in the first instance" and that "in this sense, things have indeed become a lot more egalitarian?"

In my gentrifying 'hood, I feel like it's extremely easy to sit on your porch and tell the gentrifiers apart from the working class. Arguably, I suppose, that's because class divisions in DC tend to correlate highly with racial ones, but even so it at least seems to me as if members of the black middle class are readily identifiable as such. Of course the trouble with any contentions one might make about this is that they're hard to falsify since I'm not running around asking people whether or not they went to college or how much money they make.
