However, the story of inequality within nations is rather different. For much of the rich world, the first half of the 20th century saw the gap between rich and poor close, but since the 1980s the richest 1% has claimed a larger and larger share of GDP in countries such as the United States, United Kingdom, Canada, Ireland and Australia[5] with the proportion of wealth residing in the “middle tier” actually shrinking from 62% to 45% over the past 40 years in the USA for example.[6]
Driven by global competition for investment, many emerging economies are taking advantage of their lower labour costs, leaner government and more permissive regulatory environments to offer generous tax breaks and low rates of taxation overall. This is leading to an explosion of wealth, but also fuelling inequality.
Between 2006 and 2016 the number of Ultra-high net worth individuals (UHNWIs)[7] grew globally by 42%, from 136,200 to 193,490. This growth is set to be maintained, with Knight Frank estimating that between 2016 and 2026 the number of UHNWIs will grow by 43% to reach 275,740.[8] Just eight men now own the same wealth as the 3.6 billion people who make up the poorest half of humanity.[9]
