Only some who use the Euro are richer, rov. Those in France and Germany are (for the moment) OK. The PIIGS are now seeing the chickens coming home to roost. They cannot pay their debts because their currency is overvalued and they cannot attract inward investment and foreign spending. Just look at the number of UK holidaymakers who are looking for better value by travelling beyond the Eurozone.
You expressed a similar sentiment in an earlier question:

and I can only reiterate what I said then. The strength of the Euro is one of the principle causes of the peripheral Euro nations’ troubles, not a result of them. If the markets were allowed to find their proper level those nations would have devalued their currency, but the Greek or Portugese Euro cannot be devalued in isolation and therein lies the rub. The recent devaluation of the pound against the Euro is (mainly) the price the country is paying for the preposterous spending and borrowing spree the previous government undertook.
The single currency forces widely disparate economies to adopt uniform interest and exchange rates and simple economics dictates that this cannot be sustained. It is only the stubborn vanity of the politicians, who are spending billions of taxpayers’ hard-earned propping up these ailing economies, which is preventing the inevitable. But the markets will eventually prevail (hopefully before all the cash runs out) and a default by one of the troubled economies is inevitable. Once that happens the whole house of cards will come down and it remains to be seen precisely what effect this will have across the continent.
