Twenty years ago everyone seemed to be moving out of cities which were full of grime and crime. These days everyone seems to be moving back in because that’s where everything seems to happen. However, the high cost of real estate in most cities will mean that cities become ghettos for gays, the rich, singles and childless couples. Everyone else will be in gated suburban communities or cheap housing. BTW – Scary stat: ratio of mobile homes to houses in gated communities in the US is 1:1.
