This book looks at how sociological concepts that were first 'invented' and applied to describe social inequality in Europe were also used to understand and explain inequality in the United States. However, under very different circumstances and conditions the concepts needed to be adjusted - either through changing their precise meaning or by using related concepts. In Concepts of Social Stratification the author tries to analyse this change by looking at how some of the most prominent American sociologists have tried to conceptualise their own society while at the same time addressing the complex relationship between an assumed political equality and de facto social inequality.
