Researchers have studied the poor as
individuals, as families and households, as members of poor communities,
neighborhoods and regions, as products of larger poverty-creating structures.
They have been analyzed as victims of crime and criminals, as members of
minority cultures, as passive consumers of mass culture and active producers of
a "counterculture", as an economic burden and as a reserve army of labor—to
mention just some of the preoccupations of poverty research. The elites, who occupy the small upper stratum within the category of the non-poor, and their functions in the emergence and reproduction of poverty are as interesting and important an object for poverty research as the poor themselves. The elites have images of the poor and of poverty which shape their decisions and actions.
