Why do some people argue that the federal bureaucracy is undemocratic?

Some people argue that the federal bureaucracy is undemocratic because it operates with a level of autonomy that can insulate it from direct public accountability and electoral oversight. Bureaucrats are often appointed rather than elected, which means that their decisions can be made without direct input from the electorate. Additionally, the complexity and opacity of bureaucratic processes can make it difficult for citizens to understand or influence decisions that affect their lives, leading to a perception of disconnection from democratic principles.
