It's easy to forget that what we understand now as a liberal democracy with free press, rule of law and the right for everyone to vote is extremely young.
Just look at the time when women were granted voting rights (1).
The US, by some seen as the 'holy grail' of modern democracy, officially allowed women to vote in 1919 (ironically many of the Democratic party were opposed), had extensive voter supression such as literacy tests until the 60ies and arguably still does today.
Many European countries were not real Democracies until after WW2, or event until the fall of the soviet union.
60-70, or even 100 years is basically nothing. That's one long lifespan.
Let's see if we see it all go down in flames in our lifetimes. (Probably not. Let's hope not).
