Firstly your source has this as its mission.
"FEE’s mission is to inspire, educate, and connect future leaders with the economic, ethical, and legal principles of a free society.
These principles include: individual liberty, free-market economics, entrepreneurship, private property, high moral character, and limited government."
Hardly objective is it
Secondly this is not true.
"In March of 2017, the Associated Press reported that the World Health Organization spent more for the travel of 7,000 staffers than it did for countering malaria, tuberculosis, fighting AIDS and hepatitis, and on tackling mental health and substance abuse."
The header of the link to which your source refers says
"Health agency spends more on travel than AIDS", the text says.
"According to internal documents obtained by The Associated Press, the United Nations health agency routinely has spent about $200 million a year on travel expenses, more than what it doles out to fight some of the biggest problems in public health, including AIDS, tuberculosis and malaria combined.".
I agree the travel expenses are ridiculously high, there is no need to nisinform.
