This is an issue which affects all of us, with well-publicised research by the University of York’s Kate Pickett demonstrating that people living more unequal societies are less healthy, more anxious and more likely to be affected by crime, right across the income scale.
Research published in the Guardian showed that around 80% of Britons now think the income gap is too large, and the message has been taken up by world leaders. According to Barack Obama, income inequality is the "defining challenge of our times", while Pope Francis states that "inequality is the roots of social ills".
