Unitary, confederate, and federal government

There are several advantages and disadvantages to the unitary, confederate, and federal systems of government. The unitary government is often described as a centralized government. It is a government in which all powers held by the government belong to a single and central agency. The central government creates local units of government for its own convenience and needs. Most governments in the world are unitary. Great Britain is an example of a unitary government. The Parliament holds all the power of the British government. Local governments do exist but mainly to relieve Parliament of burdens it could perform only with difficulty and inconvenience.
Advantages of the unitary government include:
1. Less duplication of services and fewer conflicts between national and local governments
2. Uniform policies, laws, political, enforcement, and administration throughout the country
3. Greater unity and stability
4. Simpler management of the economy.
Disadvantages of the unitary government include:
1. Central government out of touch with local concerns
2. Slow in meeting local problems
3. Slow government response (for instance no state National Guard that could be dispatched in emergency, troops would have to be mobilized from national authority).
4. Easily loses track of local issues

The confederate government is an alliance of independent states. The confederate government has the power to handle only those matters that the member states have assigned to it. Usually, confederate governments have limited powers and only in such fields as defense and foreign commerce. In our own history, the United States under the Articles of Confederation, 1781 to 1789, and the Confederate States of America, 1861-1865, are examples of the form. Confederations are extremely rare in today’s world. The European Union is the closest approach to a confederation in today’s time.
