Karl Marx theorized that the working class did not rise up and over throw the ruling capitalist class because of “false consciousness”. I am definitely not an expert on the topic of Marxism so please excuse the possibly crude analysis of my reaction.
In our capitalist society there are the added factors of Government jobs, academic, and management jobs that many people can attain with relative ease. The idea that one must either own capitol or work for the capitalist is not very accurate. Also our particular society provides a very high degree of class movement. Within a generation it is easy to see a shift in class within a family for instance, either upward or downward. This makes the idea of false consciousness seem dramatically over simple. That said I still think that there are many who don’t realize that the current capitalist system is not very congruent with the idea of social justice.
