With nearly $ 100 billion in its name, Microsoft co-founder and philanthropist Bill Gates has a lot of intimidating funds to deploy.
If the Gates Foundation had invested $ 10 billion in energy projects in the developing world, the return would have been $ 150 billion, says Gates. Investment in infrastructure in the developing world would have returned $ 170 billion.
"By investing in global healthcare institutions, however, we exceed all those returns," Gates writes.
"Institutions like Gavi, Global Fund and GPEI are the closest things we have to betting to relieving suffering and saving lives," he writes in the Journal. "They are the best investments that Melinda and I have made over the past 20 years, and they are some of the best investments the world can make in the next few years."
