Drawing largely from his book, A World More Concrete, N. D. B. Connolly explores the sweeping and intimate workings of capital in the urban Atlantic World. He argues for understanding racial segregation as a process of capital extraction. He also asks us to consider the development of American liberalism as consequence of political deals and rent-seeking practices that were at once transnational, regional, and interpersonal. By interrogating the movement and concentration of people and power, Connolly casts the modern American city as a uniquely hemispheric site of opportunity and hardship. Perhaps, too, he points the way to a new approach to urban America, one that reconsiders the colonial aspects of everyday life in the twentieth-century city.
