All this talk about wealth distribution (1% of US Citizens etc. etc.) got me wondering about the wealth distribution in other periods of history when - let's call them - great edifices were built.
E.g. when the major pyramids were built, did '1% of the population' control as much wealth as the 'bottom 90%'? Was the ratio even more exaggerated?
I suppose the question could be answered with the most accurate demographics from any civilization / empire period, where a major edifice was created (great wonder, 'multi-national infrastructure', etc).
Personally, I'm curious to understand the relationship between cultural projects and wealth distribution.
