Alienation, the 'commodification' of social life, a culture of greed, aggression, mindless hedonism and growing nihilism, the steady hemorrhage of meaning and value from human existence: it is hard to find an intelligent discussion of these questions that is not seriously indebted to the Marxist tradition.

At every stage, public debate over alternative economic plans and policies would be essential. In this way, what and how we produce could be determined by social need rather than private profit. Under capitalism, we are deprived of the power to decide whether we want to produce more hospitals or more breakfast cereals. Under socialism, this freedom would be regularly exercised.

Marx was the first to identify the historical object known as capitalism - to show how it arose, by what laws it worked, and how it might be brought to an end. Rather as Newton discovered the invisible forces known as the laws of gravity, and Freud laid bare the workings of an invisible phenomenon known as the unconscious, so Marx unmasked our everyday life to reveal an imperceptible entity known as the capitalist mode of production.

Much of the media under capitalism avoid difficult, controversial or innovative work because it is bad for profits. Instead, they settle for banality, sensationalism and gut prejudice.

We will know that socialism has established itself when we are able to look back with utter incredulity on the idea that a handful of commercial thugs were given free rein to corrupt the minds of the public with Neanderthal political views convenient for their own bank balances but for little else.

Baa Baa Black Sheep’ makes Marx’s Capital look like Mary Poppins.
