end of history
The idea, posited by Francis Fukuyama in The End of History and the Last Man, that the rise of the modern liberal democracy and free market capitalism is the end of political history, the pinnacle of human society, the furthest we can go whether we like it or not. It also makes reference to Nietzsche's the Last Man.
For it's the end of history
It's caged and frozen still
There is no other pill to take
So swallow the one that makes you ill
– Rage Against the Machine, "Sleep Now In the Fire"
