Excluding dictators and royalty, there are around 2,000 people in the world who are billionaires. Some inherit wealth while others might build fortunes through inventions, businesses or investments. Some say individuals holding onto extreme amounts of money is wasteful because it could be diverted to other areas that would benefit more people such as education and healthcare. Others reason than some billionaires should keep what they have because they drive economic growth and inspire others to innovate. Are billionaires the right focus or should attention move to the systems and processes that enable them to make and keep huge amounts of money?
