The problem lies with us: we've become addicted to experts. We've become addicted to their certainty, their assuredness, their definitiveness, and in the process, we have ceded our responsibility, substituting our intellect and our intelligence for their supposed words of wisdom.

We live increasingly in a world of haves and have-nots, of gated communities next to ghettos, of extreme poverty and unbelievable riches. Some enjoy rights that are completely denied to others. Relative inequalities are exploding, and the world's poorest, despite all the advances of globalisation, may even be getting poorer.

The term 'glass ceiling' was coined in 1984. More than 20 years later, the ceiling has barely cracked. There isn't a single country in the world that has as many female as male politicians. In business, the situation is even worse. Its highest echelon - the board - remains a chauvinist's dream.
