The past decade was probably the most exuberant period of wealth creation in human history. It also produced an unprecedented number of wealthy people. Despite the recent disappearance of some well-known "dotcom" tycoons, the count of millionaires and billionaires still went up last year. Why was so much new wealth created in the 1990s? How did so much of it end up in the hands of the rich? And what are the economic, social and political implications of wealth creation when it goes hand in hand with rising inequality? This survey will consider these and other questions facing the wealthy, particularly the new rich, but will assume that they will have little difficulty finding ways of spending their money.
