For centuries, capitalism has concentrated social and economic activity in massive cities. But their development and expansion has been driven by a capitalist logic which puts profits before human life, utility and economy at the expense of pleasure and beauty. The modern concrete jungle is the result. The world’s cities are class and race-segregated, and centred on ugly towers devoted to finance and industry. Meanwhile living space is crowded and the poor are pushed to the margins; homelessness abounds while shelter is everywhere, green spaces are paved over to make way for dazzling shops. How do we understand the politics of urban development, and is there a socialist vision for the cities of the future?
