There is no doubt that the generation who have experienced fascism and world war are dying off however when it comes to millennials getting bored of liberal democracy, that is debatable.

In countries like U.S. it could be a possibility because their educational system is not on par with other modern democracies (See YouTube video “Is our children learning”).

Alternatively, millennials have seen wars in Afghanistan and Iraq and realize that dictatorship or communism are not the best form of governing.

But then again U.S. is already a police state and a one that is very similar to Russia.
