Absurd? Of course, but that is the methodology used in most reports on global wealth inequality. As the Adam Smith Institute points out, it makes no sense to look at net wealth without also examining the incomes people are likely to earn in future from wages, investments and pensions. The shock and oft-cited statistics about the share of total wealth owned by the richest are based on such misleading net wealth figures. If gross wealth were used, or if adjustments were made for disposable income and living standards, the picture would look significantly less unequal. The bottom 80pc may statistically own just 5.5pc of the world’s net wealth, but that is because they have mortgages. They control far more of the world’s assets than such numbers suggest.
