“Cities are very unequal places. They are mixtures of very rich people and very poor people, very connected people and very disconnected people, people with a big inheritance and people that are utterly disinherited. The interesting question is why – despite extreme, structural, long-term, ongoing inequalities – these places cohere in some fashion. They cohere so long as a basic premise doesn’t get violated.” Michael Ignatieff talks with CityLab about how those premises arise.
