An article by the author in the Economic and Political Weekly in the late 1960s noted that Western anthropologists had neglected the study of as a world system. The author suggests below that this has been remedied, as various social and political movememnts catalyzed a corpus of social science literature and debate. This article examines demographic and economic indicators to highlight the changing character of developed and less developed capitalist and socialist countries and its significance for social scientists. In 1967 I wrote a paper New Proposals for Anthropologists for the Southwestern States Anthropological Association meeting in San Francisco. I couldn't think of a journal in the United States that might be likely to publish it, and it was published in Economic and Political Weekly. Monthly Review republished it in 1968, as and Imperialism, after which it was translated into several languages and reprinted many times. I want first to briefly outline the problems that were bothering me when I wrote that paper and the historical background to it. I would then like to mention some of the kinds of work that have been done in North America since 1968 that are relevant to these problems. Finally, I want to talk about some of the major changes in the world which have an impact on our subject and our thinking. Anthropology and Imperialism was written at the height of the war in Vietnam. My husband, David Aberle, and I, along with a number of other anthropologists, had become deeply disturbed by the evidence of wholesale destruction of territory, villages and people by U.S. forces in Vietnam, especially by the use of anti - personnel weapons such as napalm, and the defoliation of forests and cultivated land. In 1967 David Aberle presented a resolution at the annual meeting of the American Anthropological Association which condemned those weapons. To our dismay, it was ruled out of order by the then chairperson, Frederica de Laguna, and vehemently opposed by Margaret Mead, who argued that political resolutions were in the professional interests of anthropologists. There was a commotion on the floor. David Aberle, Gerald Berreman and others argued against the chair, but the day was won when Michael Harner rose and stated: Genocide is not in the professional interests of anthropologists. Against the chair's ruling, the resolution was then passed by a large majority. It was one of the first published statements by a professional association against the war in Vietnam. There was of course an enormous outcry against the war by the U.S. public as well as by professionals in later years. The Vietnam war (or as the Vietnamese more properly call it, the U.S. imperialist war) came to an end in 1975, after about two million Vietnamese had been killed and perhaps another two million crippled. By imperialism I mean any social system in which the government and/or private property owners of one or more countries dominate the government and people of one or more other countries or regions politically, militarily, economically or socio - culturally (usually all four of those) to the detriment of most of the subordinated people's welfare. For the last 400 years, most has been capitalist. During this century, capitalist has wreaked the most harm and been responsible for the most deaths through two world wars and almost countless minor wars, as well as through starvation, malnutrition, destruction of traditional agriculture and industries and political repression by dependent, dictatorial governments. However, the Soviet Union and China have also practised forms of since their revolutions. In 1967 I tended to neglect this phenomenon because I am a Marxist and was somewhat biased in my outlook, and partly because I did not have evidence that the U.S.S.R. and China had extracted economic surplus from their dependencies, and so I tended to underestimate the political and cultural repression that they had practised. …
