Mr Gates said that the foundation's spending would increase from $6 billion a year to $9 billion by 2026 due to the recent global setbacks.
He plans to give most of his wealth to the foundation. I will leave the list of the world's richest people one day.
I have an obligation to return my resources to society in ways that help reduce suffering and improve lives. I hope that other people in positions of wealth and privilege will follow suit.
