Wage-Labour and Capital & Value, Price and Profit

The text of "Wage-Labour and Capital" came from lectures Marx delivered to the German Workmen's Club of Brussels in 1847, a time of great political upheaval. The relation between wage-labour to capital is a core concept in Marx's analysis of political economy. This book is an essential, a foundation to understanding the development of Marxist theory. "Price. Value and Profit" was written in 1865. The different parts, as in the title decomposes into 'surplus value' (the essential economic building block in Marism). This book, again, is basic to understanding the development of Marist theory.
