Germans Show No Way to Give Up on Euro Spurring Boom

For Germany, bailing out its neighbors to save the euro is proving a price worth paying.

Rising share prices and foreign sales at Bayerische Motoren Werke AG and Siemens AG show why it may be worth keeping the single currency even as some voters balk at the cost of rescuing Greece and demand a return to the deutsche mark. As exporters benefit from the lower labor costs and currency stability fostered by the euro’s 1999 introduction, unemployment has dropped close to an 18-year low and the DAX Index is the 16-nation bloc’s best performing major benchmark this year.
