Query: Challenging World and Cultural Perspective!

BRAVO! A brave and highly analytical insight into global economic and socio-cultural interaction concerning the prospect of "future history." A great read that cooks up quite a bit of what-ifs that challenge business, political and economic players of all levels to re-examin strategies and potential consequences. One must know the past to step into the future.
