while he covers the Bourgeois and the proletariat aspects of a capitalist economy, I think that he theorized too much about profit margins and failed to mention that investors looking for profit are looking for what people want to buy, i.e. demand. Also keep in mind that the book was written in a different time. Finally, although there are promises of everybody decides whats best for everybody, what I have failed to find is a motive to work in a socialist system, using his model, I'd rather have a paycheck in my name representative of the effort that I put in as opposed to getting the same amount of money as someone incapable of working.
