Who has complete control of the laws, rules, and affairs of a country

In a country with a modern democratic system, the sum of these powers and their control are not consented to a single figure, they are divided into different institutions such as the President, Congress and the Judiciary. On the contrary, in the case of countries with defective democracies or authoritarian governments, the sum of these powers is centered on a President, a dictator or a King.

is this from a story?

if so, can you tell which one?
