A mandate increases centralization primarily because it requires states to make changes, sometimes without federal funds. Mandates often impose obligations on states to comply with certain federal laws or regulations, thereby reducing the autonomy of states in decision-making. States may be compelled to implement specific policies or programs as dictated by the federal government, which can lead to a more centralized governance structure where federal authority is strengthened over state discretion.
While mandates can also involve cooperation between federal and state agencies, the key aspect of increased centralization is the requirement imposed on states to adhere to federal directives, often leading to the alignment of state policies with federal priorities regardless of local needs or resources. This centralizing effect is intensified if states are required to modify their operations or invest resources without receiving corresponding federal funding.
