Keynes, Hayek and Marx: Three thinkers with differing ideas about capitalism.

Masters of Money: A worthy video to spend three hours, either as refresher course or inaugural primer about three veins of economic thought.

BBC economics editor Stephanie Flanders examines how three extraordinary thinkers, Keynes, Hayek and Marx, helped shape the 20th century.

The Guardian's review of the 2012 series is here. Flanders keeps the conversation accessible, without hue and wonk.

Keynes ... capitalism is too important to be left to its own devices. 

Hayek ... capitalism only works when government leaves it to its own devices. 

Marx ... capitalism must die of its own devices.
