Perpetual revolutions in technology can mean the devaluation of fixed capital on an extensive scale.

Not only must weapons be bought and paid for out of surpluses of capital and labour, but they must also be put to use.

What better reason could there be to declare that it is time for capitalism to be gone, to give way to some saner mode of production?

The right to the city is far more than the individual liberty to access urban resources: it is a right to change ourselves by changing the city. It is, moreover, a common rather than an individual right since this transformation inevitably depends upon the exercise of a collective power to reshape the processes of urbanization. The freedom to make and remake our cities and ourselves is, I want to argue, one of the most precious yet most neglected of our human rights.
