I find it somewhat baffling that the ultra-wealthy are finding it challenging to hit their Giving Pledge goals as described in the article. There are several multi-hundred-billion dollar initiatives that are desperate for money that could save millions of lives per year. For example, the number of people who die from TB annually is way in excess of 1 million, with 10million+ falling ill with the disease. This is a disease for which we have the cure - and have had the cure for 80 years. TB could be ended within 6 years with a $250bn commitment. While these millions upon millions are dying, a couple of thousand billionaires donate miserly single-digit-percentages of their wealth per year, and complain that they can't find a philanthropic outlet, while reaping the publicity benefits of saying they'll give away 50% "eventually, maybe before they die". Outlets for this wealth exist, and it's not as if it's particularly challenging to pick one "save literally tens of millions of people" project over another "save literally tens of millions of people" project.
