Oxfam International, a poverty fighting organization, made news at the World Economic Forum in Davos earlier this year with its report that the world's 85 richest people own assets with the same value as those owned by the poorer half of the world's population, or 3.5 billion people (including children). Both groups have $US 1.7 trillion. That's $20 billion on average if you are in the first group, and $486 if you are in the second group. By the time Forbes published its 2014 Billionaires List in early March, it took only 67 of the richest peoples' wealth to match the poorer half of the world. Each of the 67 is on average worth the same as 52 million people from the bottom of the world's wealth pyramid. Bill Gates, the world's richest man, with a net worth of $76 billion, is worth the same as 156 million people from the bottom. Who are the 67? The biggest group-28 billionaires, or 42% of them-is from the United States. No other country comes close. Germany and Russia have the second-highest number, with six each. The rest are sprinkled among 13 countries in Western Europe, APAC and the Americas. That the biggest group of the super rich comes from the U.S. should not be a surprise, as the country holds almost a third of the world's wealth (30%), significantly more than any other country, according to the Global Wealth Databook, from Credit Suisse Research Institute.
