For every idealist trying to make a difference, you get some bureaucrat from <insert country here> who is only interested in having a title and bilking it for as much money as it's worth. Because said bureaucrat is from <insert third world post colonial country here>, firing them in favour of <idealist overqualified candidate from the G7> is impossible, and actually contrary to the mission of getting various nations to buy into the system.

I used to really believe in the United Nations. Did MUN in high school, got a degree in politics, studied how developing polities can form ideal governments, the whole nine yards. Now I write python for one of the beltway bandits. At least the problems the computer has can be solved by logic and hard work.
