My attention was originally drawn to this graphic illustration of capitalist exploitation of labor via economist David Ruccio's website which used it as a platform to discuss how wrong John Maynard Keynes was with regard to increasing wealth and leisure for working working people.
Keynes back in the 1930s tried to reform the capitalist system through re-distributive government policies. Little did he realize that capitalists would have nothing to do with such policies--they wanted it all for themselves--and they proceeded as always to shape the government to serve their needs. Thus the government became entirely as we see today: their government.
But enough of Ruccio who as a professor must not annoy his capitalist masters too much or else join the line at the unemployment office. I want to direct your attention to this political cartoon and its real source at the Capital Drawing Group in London. This group of four cartoonists have drawn numerous cartoons to illustrate various themes about capitalism based on Marx's writings.
The cartoon below illustrates "The General Law of Capitalist Accumulation" as a monster of devouring workers for the wealth benefit of the capitalist pocket shown at the top.
