For example, according to HM Revenue and Customs, in 2003, 71 per cent of all financial wealth in the UK was owned by just 10 per cent of the population. Even if we add property ownership to financial wealth, the least wealthy 50 per cent of the population only own about 7 per cent of all wealth in the UK in 2003. These figures are also likely to be underestimates, because people generally do not declare the full sum of their wealth to the tax authorities - for instance, they may keep wealth abroad.
