All three different types of government have different advantages and different disadvantages. Unitary governments are normally said to be a very centralized type government. It is a government where all the powers are held by a one main group. A lot of governments in the world are unitary. A Federal government is a type of government where the powers are split between a central government and many local governments. . A Confederate government is a type of government that has groups of independent states. A central agency has the power to handle only the matters given to it by the member states. The Confederate States of America was a type of a Confederate government. Unitary type governments are a lot of the time described as centralized governments. Unitary governments have some advantages in how they operate, such as, laws, uniform rules, enforcement, and administration through the whole country, less copying of services and fewer conflicts between national and local governments, as well as having greater compatibility and stability. Unitary governments do still have their own disadvantages too with how they work, like, the central government being out of touch with local concerns, being slow in responding to local problems, and if the central government gets too involved in local issues it may not be able to meet the needs of all of its citizens.
A Federal government is a type of government where the powers are divided between a central government and many other governments. Both levels of government act directly towards the people through their own sets of agencies, and laws. A federal government has its advantages, like federal unity but local governments handle local problems; the central government can give more time to national and international issues. A federal government can have disadvantages to, like copying services, and fights about power.
