The category of public service that has the closest contact with the political class is the administrative class. The administrative class is responsible for implementing the policies and decisions of the political class, which includes elected officials and government leaders. They work in various government departments and agencies, such as the civil service, and are involved in the day-to-day operations of the government. The administrative class has the closest contact with the political class because they are the ones who carry out their directives and provide them with advice and support. They are responsible for translating the policies and decisions of the political class into actions and ensuring that they are carried out effectively and efficiently. The manipulative class, clerical class, and technical class may also be involved in public service, but they do not have the same level of contact with the political class as the administrative class. The manipulative class may refer to individuals or groups that seek to influence or control government decision-making, while the clerical class and technical class may refer to support roles in public service such as data entry, computer programming or technical support.
