The modern face of capitalism - with 18th Century principles?

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

In this episode, the final of four, O'Regan is back in Dublin to conclude the series. So what does he learn about the capital of his homeland?

"Dublin is the epicentre of both the crisis of capitalism and causes of that crisis as well," economist Constantin Gurdgiev tell him.

After that cheerful note, O'Regan tries his (invisible) hand at mixing capitalism with a comedy club, and generating about as much humour as this sentence.
