"Contributions are held in an endowment, which must give away at least five percent of its worth each year. The other 95 percent is invested. [20] From 2000 to 2007, the endowment was managed by Bill Gates Investments, which handles Gates’ personal fortune.
In 2006, investor Warren Buffett made a lifetime pledge to the foundation of Berkshire Hathaway stock valued at $31 billion. [21] The gift is paid in yearly installments with most recent contribution of $3.6 billion on July 1, 2019. [22] To date, Buffett has contributed $24.5 billion to the BMGF.
Foundations are not permitted by tax law to contribute to candidates for election. However, the Center For Responsive Politics lists contributions from individuals who list the Bill and Melinda Gates Foundation as their employer: Those contributions total $1,006,305 to political candidates and political action committees (PACs) since 2000. Of those contributions, 88 percent, or $106,212, were made to Democratic candidates and committees.
Some have criticized the Gates Foundation by pointing to the fact there are three trustees deciding how billions of dollars controlled by the world’s largest philanthropic foundation are spent. Pablo Eisenberg of Georgetown University’s Public Policy Institute told NBC News, “That is much too small and narrow a board to run a foundation whose combined assets will one day exceed the budgets of all but 30 percent of the countries in the world,” which he said “offers little protection to America’s taxpayers or the national interest.”
The Gates Foundation has been criticized for too-broad funding through an interconnected network of organizations and individuals across academia and the NGO and business sectors which University College London Dr. David McCoy said in 2012, “allows it to leverage influence through a kind of ‘group-think’ in international health.” And in 2008 the head of malaria research for the World Health Organization accused a s-called Gates Foundation “cartel” of suppressing diversity of scientific opinion, claiming the organization was “accountable to no-one other than itself.” "
In summary: too much control and influence with too few checks and too little accountability.
