Gates says the $10 billion his foundation has put into the three organizations has created an estimated $200 billion in social and economic benefits. (The estimate is from the Copenhagen Consensus Center, a think tank that estimates cost analysis to global problems.)
“Suppose that our foundation hadn’t invested in Gavi, the Global Fund and GPEI and had instead put that $10 billion into the S&P 500, promising to give the balance to developing countries 18 years later. As of last week, those countries would have received about $12 billion, adjusted for inflation, or $17 billion if we factor in reinvested dividends,” Gates says describing the estimates from the Copenhagen Consensus Center.

Extraordinary that this should be spun into profits for Gates (or his foundation).
