Big charity projects generally named after themselves like university buildings or professional schools usually go with a net worth of $100 million at least. That is category 8 for a lucky 49,000 on our planet.
Category 9 is $1 billion and more (2700 in number); category 10 is $10 billion plus (only 150); and category 11 is over $100 billion and consists of just two people. Amazon's Jeff Bezos and Microsoft's Bill Gates are in this stratosphere capping Bloomberg's numbers.
The 26 richest billionaires own as much as 3.8 billion people, the bottom half in the world. That's capitalism.
