> To add to Dennis' comment on increased ethnic diversity of suburbia - it is quite visible here in the DC/Baltimore area. That makes me think that the main instrument of apartheid in the US is not housing anymore, but transportation.
Or a combination of the two -- older, more expensive suburbs served by commuter trains that are usually better kept and more reliable than El/subway systems and especially busses. This is very visible in Chicago and Boston.
Plus, as a friend in Chicago observed, you can drink booze on the Metra.
