In 2014 Thomas Piketty, a little known French academic economist, published his global bestseller Capital in the Twenty First Century. This book, all of 900 pages long, captured the spirit of the age. Piketty’s book reflected a growing concern about the enormous inequality that has blighted western societies at the beginning of the 21^st century.

Piketty famously stated that returns on capital grew faster than the incomes of the poor, leading to even greater inequality. Piketty’s arguments were welcomed by a world ever conscious of growing inequality.

The success of the so called ‘1%’ – bankers, financial speculators and entrepreneurs who control so much of modern wealth – is clearly visible. But what should the response of politicians be to growing inequality? How can we reconcile the obvious need to grow the economy while ensuring the weakest and most vulnerable in society do not get left behind?

A number of measures have been introduced to make sure that the rich pay their fair share in taxation. In Britain alone we have had increases in stamp duty and, in the last six years, increases in capital gains tax. Socialist France, under the leadership of Francois Hollande, introduced a 75% income tax for incomes over 1 million euros a year. Hollande’s government increased this tax before Piketty’s bestselling book was published. A “soak the rich” atmosphere has been prevalent in many developed countries since the financial collapse of 2008.
