On social structure of post-soviet Russian society is based of sociological data obtained by the author in the course of regular monitoring in Moscow, Saratov, and Saratov oblast' during early 1990(th) and repeated in 1999-2000. Comparisons were made with 1970(th) and 1980(th) studies of similar programs. Comparative analysis permitted to follow up changes in social structure along with the multitude of social changes especially linked to emergence of private property. Here, a main result is marked social polarization that in its turn had significantly influenced employment chances, career opportunities and professional growth, as well as chances to participate in economic decisions in specific production units. It is concluded that were these processes to continue with ruling elite unable to cushion impact, threatening situation might arguably emerge leading to unpredictable results.
