According to the Bloomberg Billionaire Index, the world's 500 richest people grew their fortunes by 25% in 2019. Further, the combined net worth of the world's 2,816 billionaires totals $11.2 trillion. That's more than the total GDP of almost every single country in the world, except for the U.S. and China. Those numbers are absolutely staggering. What's even more impressive is the fact that most of the world's top 10 wealthiest people are entirely self-made. That means they didn't inherit their fortunes, but instead either founded major companies or made some incredibly wise investment decisions.
