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).

I am suggesting that there is, and always has been, a rather high correlation between ethnicity and occupation/economic role throughout the various time-space zones of historical capitalism.

Are there still other possibilities? Of course there are. What is important to recognize is that all three historical options are really there, and the choice will depend on our collective world behavior over the next fifty years. Whichever option is chosen, it will not be the end of history, but in a real sense its beginning. The human social world is still very young in cosmological time. In 2050 or 2100, when we look back at capitalist civilization, what will we think?

This argument has been codified in the twentieth century as meritocracy, in which those on top in the process of capitalist accumulation have merited their position.

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.

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.

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.
