The fourth branch of the United States government is a conglomerate of administrative agencies funded by public money to help in the expansive sharing of powers. In many instances, this unofficial arm of the government gets delegated with decision making duties by the U.S Congress; hence raising some concerns.
One of the major concerns raised is that though these people continue making decisions that directly affect citizens, it is nearly impossible to remove them from office. This is because they are not elected by citizens but rather, some are appointed by the executive, and thus, they can serve other interests than those meant to benefit citizens. In case of manipulation by the executive arm of the government, such people can continue holding office even though citizens are not comfortable with their leadership. Consequently, with more delegation of decision making by the Congress, citizens may feel that they are not being served the way they should be served.
Another concern that might arise from tasking the fourth arm of the U.S government with decision making is that they are not directly accountable for the decisions they make. For instance, in case decisions made have negative consequences to citizens, this unofficial arm of the government takes no direct accountability. This means that this arm stands to lose nothing. In the long run, this may lead to impunity, and carelessness in decision making thus making the arm a subject to not serving the purpose it is intended to serve. Therefore, the major concerns are that the agencies are not directly accountable for the decisions they make and removing them from the office is difficult.
