One of the saddest stories of the 20th century is the fate of air travel. In 1900 it was a dream, feverishly speculated upon, subject to all manner of Jules Verne imaginings; by 1999 it was a chore, a tedious, uncomfortable ritual undertaken in order to get from A to B.

Two September shocks will define the presidency of George W. Bush. Stunningly enough, it already seems clear that the second -- the financial crisis that has only begun to unfold -- may well have far greater and more lasting ramifications than the terrorist attacks of Sept. 11, 2001.

That's because while 9/11 changed the way we view the world, the current financial crisis has changed the way the world views us. And it will also change, in some very fundamental ways, the way the world works.
