I think the Guardian article meant that they had subtracted debt from assets, but they stated it in a confusing way. The original report states:
Once debts have been subtracted, a person needs only USD 3,210 to be among the wealthiest
half of world citizens in mid-2015. However, USD 68,800 is required to be a member of the
top 10% of global wealth holders, and USD 759,900 to belong to the top 1%.
Which is more clearly stated and uses the same numbers as the Guardian article.See page 11 from: https://publications.credit-suisse.com/tasks/render/file/?fi...
