There's an unequal distribution of income and opportunity between different groups in almost every country in the world. In most countries millions live in poverty, millions more are comfortable, some very comfortable, and a few are extremely wealthy. Income inequality has grown in over recent decades, and wealth inequality is heading in the same direction. There are inequalities in education, life chances, health, longevity and political power.

Our instincts tell us that it is morally wrong to allow these kinds of inequalities to exist, but is it a really a problem we can or should solve? Why might it be important for us to reduce income and wealth inequality? And what role does policy have to play in its creation, and potentially its elimination?

Paul Johnson is a man in the know, with a deep understanding of the data. Paul is the Director of the Institute for Fiscal Studies, the UK's leading economic research institute. He's joining us in The Garden to make sense of how today's economic inequality has arisen, and explore whether we could, or should, do something about it.
