What is different in capitalist civilization has been two things. First, the process of meritocracy has been proclaimed as an official virtue instead of being merely a de facto reality. The culture has been different. And secondly, the percentage of the world's population for whom such ascent was possible has gone up. But even though it has grown up, meritocratic ascent remains very much the attribute of a minority.
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 first and probably most fundamental aspect of this crisis is that we are now close to the commodification of everything. That is, historical capitalism is in crisis precisely because, in pursuing the endless accumulation of capital, it is beginning to approximate that state of being Adam Smith asserted was 'natural' to man but which has never historically existed. The 'propensity [of humanity] to truck, barter, and exchange one thing for another' has entered into domains and zones previously untouched, and the pressure to expand commodification is relatively unchecked.
