A low euro is good for German exports, which is one bright spot. However, overall the German business world is disappointed.
Funnily enough, a Grand Coalition under Schröder with the CDU as junior partners might be quite popular. In all polls, Schröder was consistently the preferred Chancellor compared to Merkel by a very wide margin, however the red-green policies were perceived as a failure. If Schröder now implements changes (say, with a CDU finance minister and/or economics minister), the necessary reforms could go through after all!
