Nobody was forced but somehow something was missing, i tried to find reasons why these failed, it's a complex blend of mild poverty, mass social dynamics (same problems as in other neighborhood except it's not in higher concentrations and become unmanageable quick, broken window + reputation + tribalism). It devolved too fast to be handled. Even though on paper, they had best in class standards of living for average citizen (at that time my aunt lived in flat in Paris without toilets, it was the way for old building in her paris area; a year later she had electric kitchen appliance and her own toilet/bathroom).
