Accumulation by dispossession is a concept presented by the Marxist geographer David Harvey. It defines neoliberal capitalist policies that result in a centralization of wealth and power in the hands of a few by dispossessing the public and private entities of their wealth or land. Such policies are visible in many western nations from the 1970s and to the present day. Harvey argues these policies are guided mainly by four practices: privatization, financialization, management and manipulation of crises, and state redistributions.
