The only people on the rich list are the parvenus like Bill Gates and Jeff Bezos. The really rich seem to hide their money in various trusts, and avoid paying taxes on their wealth. I read a report by an ex-banker who estimated that almost half of the total wealth of the world is controlled by the City of London. Of course this is done through a variety of trusts in tax havens such as Jersey, The Cayman Islands and others. Property is hidden by using a hierarchy of holding companies and trusts ( a British invention ). There is even a name for it, it is called "The veil of Tiers".
thats because the west fools its own population with their central banks, and only works by fooling the population, the average citizens are supposed to live in a dream world, where they feel big and strong, but they are in the end just those low net worth individuals.
that are supposed to sell their time, while the capitalists print money and buy their time and live in wealth and security. the proletarians live in unsecurity.
