You can disagree with what Fukuyama wrote in "The End of History" but what he wrote isn't what most people (who haven't read it) think he wrote. The strawman version that most people think he wrote is "Yay! The Cold War is over! Everyone will instantly become democratic and capitalistic!". What he actually wrote is that democracy and capitalism is the eventual end state of human society, even if it may take centuries to get there for everyone. I think history shows that dictatorships and economic systems that deny market forces are ultimately short lived. Yes, right now democracy and capitalism have a lot of detractors, and it may be that these will temporarily fail even in some Western countries. But even if they do, I doubt these new regimes will last long and eventually people will have to go back to what works.
