The big difference is in the social housing model rent is on a sliding scale so you get a mix of incomes. In America public housing was only for very poor people. America's public housing era also coincided with deindustrialization, the end of full employment, and the neoliberal turn. Good social policies work together. When some policies are neglected the policies that exist get blamed for the overall failure. For example, in America there's poverty, so schools in poor areas are blamed. Nobody in rich suburbs wants charter schools. The problem is obviously economic policies that cause poverty, not the schools, but because there's no full employment policy, the schools get blamed.
