As the financial markets are hardly taxed at all, the introduction of a traffic tax for financial transactions is urgently overdue. As early as 2012, 11 member states basically agreed to introduce a corresponding financial transaction tax on a cross-border basis. However, the tax has not yet been implemented because the states were unable to agree on a concrete form. This political stalemate must now finally come to an end. Every year, without tax, citizens pay billions of euros. According to calculations, the planned moderate financial transaction tax would bring the member states a good 50 billion euros a year. In view of the fact that the EU states supported the financial sector in the economic and banking crisis of 2008 to 2010 with approx. 4.6 trillion euros, this taxation would even be a drop in the ocean. The financial transaction tax must therefore be introduced promptly and set significantly higher. With a tax rate of only 0.5% on trading in shares, annual revenues of a good 250 billion euros could be realised. The financial markets are finally more strongly to be taken in the obligation, who claims in times of crisis trillions of tax money, must participate in times of growth also appropriately in the common good.
