Problem is that in the 1930's, the world was extremely different and a recovery was much easier to achieve. Today with global markets so tied up together, the health of so many national economies being dependant on orgs like the World Bank, etc. , floating of global currencies, financial speculation, greater market fluidity, etc. etc. etc..... well, things may recover (and lets hope they do) but there needs to be a move away from fundementalist ideology controlling political and business decisions or global disaster is inevidable sooner or later....
