The better schools and living conditions in the US are in the suburbs, which contain a lot of people who work in the cities, or have other interests there. In order to get out of the drawbacks of living in a city, they move to the suburbs. I believe random thoughts was making the point that European cities have fewer of those issues which drive the better classes of urbanites out. The example he used was busing, in which case the solution is to move out of the city, to a suburban school district of your choice, rather than stay in the city, under the authority of their education bureaucracy and its social experiments.
