Reducing wealth inequality is arguably the greatest challenge of our times. The world’s 2,153 billionaires hold more wealth than 4.6 billion people – equivalent to 60% of the population. The most affluent 162 individuals have assets equal to the poorest half of the world. Individuals owning over US$100,000 in assets make up less than 11% of the global population but own 82.8% of global wealth, while adults with less than $10,000 make up 56.6% of the world’s population but hold less than 2% of global wealth. The United Nations has named the reduction of poverty and inequality in its 17 Sustainable Development Goals – first and tenth, respectively.
