“Wow. I remember a few days ago when stuff like this seemed really important.” This bulletin board message was how one so-called ‘greedy associate’ reacted to talk of West Coast job cuts in the wake of last week’s terrorist attack on the World Trade Centre. Many people will have had similar thoughts in the aftermath of the attack on the heart of America.

But, of course, as well as committing mass murder, the attackers also hoped to disrupt the world economy. There have been signs both in America and across the world of a determination among business leaders not to let this happen – or at least to minimise the economic impact of the attack.
