The pooling of artists in global cities has become a destructive anachronism; destructive to artists, working-class communities in those cities, and destructive to art itself. 

The formation of art enclaves in industrial capitalism, during a century of accelerating aesthetic and conceptual innovation (1850-1950) had a progressive logic. Artists’ innovations fed off their physical proximity to each other. Moreover, these aesthetic and conceptual interventions were often in political sympathy to the industrial working-class concentrated in cities like London, New York, Paris and Berlin. Artists found a radical, and oftentimes working-class, cosmopolitanism in these artistic enclaves. Gentrification had not yet evolved to exploit artists as it does today.
