It seems to me the only pertinent question is: cui bono? It is clear that the size of the privileged strata as a percentage of the whole has grown significantly under historical capitalism. And for these people, the world they know is better on the whole than any their earlier counterparts knew.
Immanuel WallersteinWars between states and people seem to have existed under all historical systems for as long as we have some recorded evidence. War is quite clearly not a phenomenon particular to the modern world-system. On the other hand, once again the technological achievements of capitalist civilization serve as much ill as good. One bomb in Hiroshima killed more people than whole wars in pre-modern times. Alexander the Great in his whole sweep of the Middle East could not compare in destructiveness to the impact of the Gulf War on Iraq and Kuwait.
Immanuel WallersteinThe mark of the modern world is the imagination of its profiteers and the counter-assertiveness of the oppressed. Exploitation and the refusal to accept exploitation as either inevitable or just constitute the continuing antinomy of the modern era, joined together in a dialectic which has far from reached its climax in the twentieth century.
