So what’s the alternative?
How do you explain what’s happening in Argentina?
Wiki: "The government of Argentina, within the framework of a federal system, is a presidential representative democratic republic. The president of Argentina is both head of state and head of government."
I'll explain Argentina as I might these United States.
By way of comparison, the German parties NOT the AfD are discussing how to disenfranchise about 1/4 of the electorate. The British Parliament has "lords" in it, and the EU parliament is most ineffective with many "member states" -- as the European elite wish sovereign nations to think themselves -- often pressured by the European Commission atop the system; that EC is not elected by the people."
By way of comparison in terms of a republic, the Soviets and the East German government called themselves "republics" but were not, without opposition politics. In the same way, other "republics" in name only us the word to camouflage their true authoritarian natures.
I would do better with definitions, but there are many sources available. Argentina's Javier Milei is cutting the size of government. Who argues with that? Government employees, and those politicians who use such employees to seek rent and profits from a people.
