“When counting wealth among all adults, data show that its value has increased more than threefold since 1980, and nearly 10 times over the past century. Since much of this wealth growth has occurred in the types of assets that ordinary people hold – homes and pension savings – wealth has also become more equally distributed over time. Wealth inequality has decreased dramatically over the past century and, despite the recent years’ emergence of super-rich entrepreneurs, wealth concentration has remained at its historically low levels in Europe and has increased mainly in the US.”
