We explore the anxieties of the wealthy, and the mentality of conspicuous consumption, which is about more than being discreet about high-end purchases. Journalist Rachel Sherman tells us her accounts of interviewing some of New York's elite wealthy - who are equally as stealthy about their endeavours and purchases. We hear more about the anxiety associated with wealth, both earned and inherited, including the constant need to seem 'normal', and justify funds. Stephen Lussier, a chief executive from diamond company De Beers, tells us about the changing buying habits of some of the world's richest - including the increasing number of women who prefer to buy their own diamonds for reasons other than romance. Plus, extravagant signs of wealth are at their peak during India;s wedding season. Weddings can go on for days, and include thousands of guests and private chartered planes, and over 70 types of food. The BBC's Rahul Tandon reports that some Indian states are cracking down on what they say are 'excessive' affairs.
