Also, in West Germany, the Deutsche Mark (1948-2002) is strongly associated with the post-war economic boom. It's still a common rhetoric among conservative populists to argue for a return to the good old times ^W Mark.
I don't think it is just a "common rhetoric", but rather a common mainstream truth that the change from the Mark to the Euro (which can be kept weaker) allows German companies to export cheaply while making people's salaries and savings worth less.
