The reverse. On second thought, it's not necessarily true. High tech does however assume a large value added per labourer and a set of highly qualified labourers and is thereby not necessarily suited for mass employment (it did pay off in Bavaria, but Bavaria did not have bad unemployment figures). Many East German areas are now also following this track, building up science parks and venturing into biotechnology. It's not necessarily something that will provide big employment opportunities for the inactive workforce existing there.

Except for the green technologies, which only have upsides, of course ;-)
