I am German but have been living abroad for nearly ten years and no longer involved in whatever goes on on a political level, etc.
All in all I'd say German banks and institutions are very traditional and highly regulated so the exposure to suprime mortgage has been slim, -however as the US and the UK are going under there are repercussions for the German economy as it is the biggest exporting country in Europe (car manufacturers, technology firms, building companies, etc.)
The level of unemployment has shrunk from record highs under Schroeder to a smaller number under Merkel. For all vital statistics pls check: www.daeb.de/statistik/index.php
Still, with a very stable and high Euro export is shrinking, too. But it's not at an alarming rate and don't forget that Germany has excellent ties to China. That should help...
Germany and Germans are quite environmentally conscious and adhere to recycling, etc. They'll happily invest in new (green) technologies and building standards. etc. have incorporated a new green ethos. That didn't stop Merkel paying out subsidiaries to the coal industry (go figure...)
As you're able to read & write German I can only recommend you to read up articles in the FAZ or Sueddeutsche Zeitung.
Good luck with your essay!
