Advanced telecommunications, computer and transportation technologies are being used to dramatically transform the structure and dynamics of the economy, both in the U.S. and around the globe. Jobs and whole industries are changing, with significant implications for economic and social opportunities. New communications infrastructures simultaneously facilitate the intense concentration of economic control, and facilitate the diffusion of business and service networks across international distances. New communications technologies support economic agglomerations of unrivalled size and complexity, while also collapsing the barriers between the ‘local’ and the ‘global’, allowing some economic spaces to be more globally connected than locally tied in to their social milieu. Thus, these technological and economic changes are everywhere implicated in the growing inequality and social divisions that seem to be evident in all societies, as global connections are combined with local disconnections in complex ways.
