Suzanne Collins has created this country ruled by President Snow and in essence Panem, is a prime example of a totalitarianism regime. The Hunger Games display this perfectly in that each district is voluntarily sacrificing 2 innocent children each year as symbols for the capital showing that they hold the power in all that they do. Pavlik states, “the Hunger Games were instituted as an annual reminder that rebellion against the Capitol should never again be considered.” It's obvious that nobody would willingly sacrifice innocent children because the government said to because there is no sound reasoning behind it.
The easiest example to identify a current day totalitarianism example is to look at North Korea. Although it is labeled as a "democratic republic," their ruler still has complete control over all aspects of life so it is in fact under complete control. These types of governments still exist because the citizens just go along with what they have. Change is hard for people and why change something that is not totally broken?
