The essay aims at highlighting some fundamental paradoxes affecting the very structure of the European Union in its current organization. The currency union is not only insufficient, but ultimately impairing the economic efficiency of the Eurozone. The economic issues that the European Union project was designed to respond to do not correspond to the present circumstances. The European institutions and the European left-wing parties have lost sight of the proper parameters of social justice. Left-wing parties endorsing pro-capital policies and supranationalism deployed to overcome nationalism are the two main paradoxes that have a damaging impact on the present development of European institutions.
