Actually, three trillion euros might be just the stimulus the Euro Zone needs. However, I wouldn't deploy it quite like that. Perhaps one trillion on renewable energy and distribution infrastructure, another on efficiency improvements and the last on a job guarantee for those still unemployed. And it probably should be spread out over three years. After all, the USA had an $800 billion stimulus which helped, but many argue that it was only half the size needed.
