Those "credentialed technocrats" are implementing the laws, as written by the Congress of the United States of America. The President is supposed to execute the laws that Congress passes, and to spend money as Congress appropriates it. He does not have carte blanche to do whatever he would like with the Federal government. There are some areas where the President has more freedom of action (like foreign policy), but when it comes to administering government, he is not all-powerful.
