This seems really odd in an Indian perspective because In India , almost every single major government organization is headed by bureaucrats or people who specialize in their specific fields who are not elected politically , but are rather selected based on merit as they have to qualify for the position through exams conducted by Public service commission (Which are some of the toughest exams to qualify and is open to everyone) .
For example , scientific Organizations like ISRO or BARC are headed by scientists , unlike NASA or Department of Agriculture or EPA where the administrator of these organizations aren't experts or don't specialize in their respective fields.
Note - Though the administrate might be experts , but that's definitely not the case in most of the cases (especially in the trump administration).
1. We have every reason to fear Trump’s pick to head Nasa
2. EPA Chief Scott Pruitt Says the Bible Teaches Us to 'Harvest' 'Natural Resources' Like Gas, Oil and Coal
3. EPA Chief Pruitt Refuses to Link CO2 and Global Warming
Why has such a system been created in U.S. ? Is there any equivalent of India's Public Service commission in U.S. ?
