The same shift towards a confined, highly monitored childhood took place in the US, corresponding to the great suburbanization. The suburbs grew due to white flight from the cities, following their colonization by blacks and the de facto ban on community defence enforced by the civil rights act.
Suburban municipal architecture is largely comprised of informal defensive barriers that prevent undesirable elements from penetrating the neighborhoods undetected.
This enables middle class parents to deniably insulate their children from the worst consequences of diversity, but at the cost of raising their children in open air prisons, in a stifling social atmosphere characterized primarily by a brittle insistence upon euphemistic avoidance of direct acknowledgement of the real issues. “Racism is simply terrible! We just wanted to live somewhere with good schools.”
Children brought up amidst the tedious fakery of the suburbs naturally become attuned to the pervasive hypocrisy of suburban white culture. They have to: simply navigating this culture requires the ability to understand the unsaid, while pretending that one has not understood it. Combined with the open air prison environment inhibiting emotional development, this is a powerful recipe for induced neurosis.
There are only a few possible outcomes: 1) they become cowardly hypocrites themselves; 2) they reject the hypocrisy and become fanatical anti-white race communists; 3) they reject the hypocrisy and become fascists.
