This blog post analyzes the texts posted to Tumbler by We are the 99% / Occupy Wall Street protesters. It finds that the concerns voiced by the protesters are consistent with pre-modern demands by peasants living in feudal conditions. The blogger doesn't use the word "feudal" but he does reach the conclusion that people today have been put in positions more similar to peasantry than to the historic American working class or any other contemporary senses of social strata.
