It is historically the case that virtually every new zone incorporated into the world-economy established levels of real remuneration which were at the bottom of the world-system's hierarchy of wage-levels.
Immanuel WallersteinThe second reason why we haven't observed the growing gap is that our historical and social science analyses have concentrated on what has been happening within the 'middle classes' - that is, to that ten to fifteen percent of the population of the world-economy who consumed more surplus than they themselves produced. Within this sector there really has been a relatively dramatic flattening of the curve between the very top (less than one percent of the total population) and the truly 'middle' segments, or cadres (the rest of the ten to fifteen percent).
Immanuel WallersteinProduction for sale in a market in which the object is to realize the maximum profit is the essential feature of a capitalist world-economy. In such a system production is constantly expanded as long as further production is profitable, and men constantly innovate new ways of producing things that will expand the profit margin.
Immanuel WallersteinCommunism is Utopia, that is nowhere. It is the avatar of all our religious eschatologies: the coming of the Messiah, the second coming of Christ, nirvana. It is not a historical prospect, but a current mythology. Socialism, by contrast, is a realizable historical system which may one day be instituted in the world.
