What can be done to mitigate the persistent social segregation of secondary schools in England?

The most coherent explanation of segregation is in terms of classed practices but not crudely as the middle class abandoning the working class. The great social distance between the most advantaged and the least, the benefits of solidarity and the restrictive effects of social policing lead the majority of both affluent and poor parents to opt for segregated schooling. School segregation first expresses and then sustains great social distance and the lack of mutual respect and civility that it engenders. It is more symptom than cause.
