Irrational actions are those in which the entity in some way defeats its own purpose, doing what is calculated to frustrate its ends. But if the big government’s policies enable it to usurp several new powers and eviscerate the political opposition then it is not frustrating its own ends.
There is, in most cases, a carefully designed strategy behind what may seem like irrational and destructive policies of the big government. There is a method behind what may seem like madness.
A big government is a government that has metamorphosed into a powerful mafia organization. It is no longer concerned with protecting the rights and liberties of the people. The fate of the citizens is not the priority. The fate of the regime is the most important of all considerations for the big government.
The big governments planners intentionally develop policies that will create a major crisis in the lives of millions of citizens because their plan is to use the crisis as an excuse for increasing manifold the powers and the size of the government. The consistency in never letting a major crisis go waste cannot be termed irrational.
A big government that rocks the country with one crisis after another can be fully rational. It can be accused of villainy of the most venal kind, but not necessarily of irrationality.
