David Harvey has suggested the term accumulation by dispossession to capture the necessarily enduring role of primitive accumulation in the development of mature capitalism, particularly within "the new imperialism."

Last but not least, in socio-political terms, there is a close relationship of strategic importance between the relative weight of accumulation by dispossession in a given period, and the need for exploited wage earners to build alliances with other dispossessed layers of the population
