The 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).

It is not surprising that liberals believed in progress. The idea of progress justified the entire transition from feudalism to capitalism. It legitimated the breaking of the remaining opposition to the commodification of everything, and it tended to wipe away all the negatives of capitalism on the grounds that the benefits outweighed, by far, the harm.

The world system is coming to the structural crisis

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.

We seem to be in the midst of a process of cascading bifurcations that may last some 50 more years. We can be sure some new historical order will emerge. We cannot be sure what that order will be. Concretely, we may symbolize the first bifurcation as the effect of the world revolution of 1968 which continued up to and including the so-called collapse of the communisms in 1989, the social bifurcation.

Finally, states have monopolized, or sought to monopolize, armed force.

What distinguishes the historical social system we are calling historical capitalism is that in this historical system capital came to be used (invested) in a very special way. It came to be used with the primary objective or intent of self-expansion. In this system, past accumulations were 'capital' only to the extend they were used to accumulate more of the same.
