David spent a week in deepest Aargau teaching a group of grammar school kids about the economy. This is one of many “Wirtschaftswochen” that are given all over Switzerland and in Swiss schools elsewhere, organised by the Schmidheiny Foundation. These weeks have been held for over forty years! The kids in Wohlen had to steer their four “portable grill production companies” through five years of decision making. We also went on an outing to a local production company, Montana.
