Introduction:
In a federal system of government, power is divided between the national government and regional governments. Whereas, in a unitary government system, power is concentrated in the hands of the national government. In this response, we will discuss why a federal system of government is better than a unitary system with the example of Belgium.

Greater Representation:
In a federal system, the regional governments have greater representation and decision-making power. This allows for more diversity in governance and better representation of regional interests. In Belgium, for example, there are three regions with their own parliaments and governments – Flanders, Wallonia, and Brussels. Each of these regions has its own unique culture, language, and political views.

Sharing of Power:
In a federal system, power is shared between the national and regional governments. This ensures that the national government does not become too powerful and overstep its boundaries. It also allows regional governments to have greater autonomy in decision-making. In Belgium, for example, the federal government has powers over defense, foreign affairs, and justice, while the regional governments have powers over education, culture, and public works.

Consensus Building:
A federal system encourages consensus-building and compromise between different levels of government. This is because decisions must be made collaboratively between the national and regional governments. In Belgium, for example, the federal government and regional governments must work together to make decisions that benefit the country as a whole.

Conclusion:
In conclusion, a federal system of government is better than a unitary system because it allows for greater representation, sharing of power, and consensus-building. The example of Belgium demonstrates how a federal system can work effectively to ensure that diverse regional interests are represented and decision-making is collaborative.
