This won't solve any of Europe's economic problems. Europe is in decline due to social decay and a fundamental lack of competitiveness. The EU chose social harmony and equality over growth and are paying the price with a stagnant society. It will take a radical shift in European nation's attitude toward work, the role of the state, and cynicism before we see real growth (however, the ECB may be successful in its attempts of inflation).
I go into further details on Europe's structural limitations here.

As for trades I like the pair trade of going long an emerging EU country such as Poland (EPOL) and shorting two of the weaker peripherals for a net short positions (Italy and France are the weakest in my opinion and the best short targets).
