The final episode of Masters of Money was broadcast this week. Karl Marx was the subject of this week's episode, and the perspective which Stephanie Flanders took was on saving capitalism from the capitalists. This was, in my estimation, the best of the three episodes. You can watch it on iPlayer.
The three volumes of Marx's capital are difficult reading, but his Communist Manifesto, written with Friedrich Engels, is short and very readable. The Kindle version is free on Amazon.
