Currency changes are never profitable, you always have to be a conversion percentage and you buy them more expensive then you can sell them. Oh yes you can make money with currency exchanges if you do it right. But as a company you did not have the luxury to choose which currency you would be paid in, you got what was common there. Big companies lost millions of euros a year on currency exchanges alone.
Prices increase every year and it's not the Euro that made the prices more expensive in itself. It's the shops, the restaurants, the bars etc. who increased the price beyond that what would have been acceptable given the introduction of the Euro.
And who says how good or bad economy would have been without the Euro? There is no way you can tell. Unless all non-Euro countries have a blooming economy of course.
