I remember a discussion with someone who lived in a French equivalent (perhaps not as bad), at the time those were being constructed (from the 50' to the 70'). At the time, people who started living there were happy, because the alternative were shantytown/slums. Of course it didn't last, but I found it interesting to see this viewpoint.
They probably worked well for 10 years. The ghettos in France are pretty bad right now too. Maybe what was missing was reinvestment in these areas, the development of services and building out the community. London and the UK have experimented with transitioning council flats to owner occupied for example. Gentrification maybe too?
From what I've heard, such areas have received and continue to receive public money, but it doesn't look like it's working. Or I am wrong and such money don't exist/go elsewhere (grafts, corruption, public money waste or just area that aren't too bad). Or the places where it's working aren't those we're hearing about (the squeaky wheel get the grease and all that).
