This future scenario is the result of increasing globalization combined with the free movement of people. International trade surges, borders become porous, nations shrink their states, public services disappear. Here is a world of rising inequalities, polarised between a tiny elite of superannuated non-doms living in island tax shelters and piles of migrants pressed into slum mega-cities with all their congestion, overcrowding, constant construction and waste. An image for this scenario might be Lagos, with its inhabitants scavenging for a living on the rubbish dumps under the city’s viaducts. The Olususun dump has about 1,000 people living on it, with improvised dwellings, shops, restaurants, bars and even a mosque. See the pictures: http://news.bbc.co.uk/1/hi/world/africa/8595108.stm
