This planetary deficit of opportunity and social justice is captured in the fact that more than one billion people, according to UN-Habitat, currently live in slums and that their number is expected to double by 2030. An equal number, or more, forage in the so-called informal sector (a first-world euphemism for mass unemployment). Sheer demographic momentum, meanwhile, will increase the world’s urban population by 3 billion people over the next 40 years (90 percent of them in poor cities), and no one – absolutely no one – has a clue how a planet of slums, with growing food and energy crises, will accommodate their biological survival, much less their inevitable aspirations to basic happiness and dignity.
