Recently, with the publication of Capital in the twenty-first century (2014), research on economic inequality experienced long not seen prominence within public debate, most notably, enabling a discourse about the distribution of wealth. Gabriel Zucman (2015) sheds light on a highly-related phenomenon – the problem of tax evasion in tax havens – with importance particularly for European countries. However, the most promising potential solutions lie on international level cooperation. The European Union thus may play a major role, advancing progress in the fight against tax evasion.
