Milton v Keynes: 20th Century capitalism and the role of the state

Comedian and writer Colm O'Regan casts his comic lens upon the complexities of capitalism.

In this episode, the third of four, O'Regan visits London, "the home of capitalism".

He investigates the ideas of John Maynard Keynes and the notion that capitalism could be "humane" - primarily through state intervention.

The opposite view, advocating a minimal role of the state and less regulation, was later espoused by Milton Friedman.

And if you roll these two great economic thinkers into a dodgy pun, you get a place not far from London.
