Like Marx, Engels believed that capitalism was inherently exploitative, as it allowed a small group of capitalists to accumulate wealth and power at the expense of the working class. He argued that the concentration of wealth and power in the hands of a few would eventually lead to the collapse of the capitalist system, and that a socialist revolution was necessary in order to transition to a communist society. Engels' book The Condition of the Working Class in England provides a detailed analysis of the living and working conditions of the working class in 19th century England, and exposes the widespread exploitation and poverty experienced by the working class under capitalism.
