According to UBS' 14th annual global wealth report just released, the amount of wealth in the world is set to rise substantially even as inequality declines. The story of the 19th and 20th centuries was broadly one in which new wealth went mostly to the rich — both in terms of individuals and in terms of countries. That is now changing, fast as total global wealth is expected to rise by 38% in the next five years — with middle-income countries, rather than the ultra-rich, reaping the majority of the benefits.
