Efficiency in Decision-Making:
In a democracy, having power reside with one person or group located at one place can lead to quicker decision-making. This centralization allows for prompt action to be taken in times of crisis or when urgent decisions need to be made.

Accountability:
When power is concentrated, it is easier to hold those in authority accountable for their actions. This accountability is essential in a democracy to ensure that the leaders are acting in the best interest of the people they represent.

Unity of Purpose:
Having power centralized can also help in maintaining unity of purpose within the government. This ensures that policies and decisions are consistent and aligned with the overall goals of the nation.

Enforcement of Decisions:
Centralized power makes it easier to enforce decisions and policies. This centralized authority can mobilize resources and coordinate efforts more efficiently compared to a dispersed power structure.

Counterpoint - Decentralization:
However, it is also important to note that decentralization of power can lead to increased participation and representation of diverse voices in the decision-making process. It can also prevent the concentration of power in the hands of a few, reducing the risk of authoritarianism.
In conclusion, while there are benefits to having power concentrated in one person or group in a democracy, it is essential to strike a balance between centralization and decentralization to ensure effective governance and representation of the interests of the people.
