It is very difficult to enter a single currency zone having fairly weak economic parameters and maintain a favourable state of the economy, not to mention positive growth rates. We have witnessed it not only in Europe, but for example in Argentina (nearly 10 years ago or more), when they tied the national currency to the dollar and later they did not know what to do about it.
But spirituality, it seems to me, when answering the question, "Why should I be good? Why should I care for others?" says, "Because that is the best, most fulfilling way to live" Whether or not you receive an award or a payment is incidental. You are good and kind and loving because it is right, even though it is difficult sometimes. It fulfills the highest law, to treat others as we wish to be treated.
