What fuel does the euro zone need to drive growth?

The euro zone is going through its worst crisis since switching to a common currency, and its leaders are wandering lost in a maze of indecision. The United States and Japan are providing a solid model for Europe to follow. Both nations are printing money while taking advantage of low inflation rates.

Unemployment is dropping in the US and Japan's GDP grew 3.5% this year. The European Commission and EU member states are under pressure to boost growth in the region. But this is a short-term solution, however necessary, under current circumstances.

The problem is the dose. Monetary stimulus works for the short-term, but it does not finance rull recovery unless reforms are strengthened at the same time. This is what European governments, especially in the south, need to carry out and explain to European citizens.
