I think it's better to see history as a series of cycles playing out over and over again.

From no existing government, to aristocratic, military government, to trade gaining power, to some sort of consensus government, eventually leading to democracy, to trade decline, to oppressive government, to self-destructing government.

Likewise and somewhat independent, society evolves from extreme liberal (like in some Greek city states, or the Roman empire, where you could rent a room in temple with a big bath where you could have sex. In the room above, a bull would be slaughtered so a stream of blood would drip down on your bodies. Note: this was marketed to women, not men, and came with an optional male partner, I think even the Kardashians would consider that going more than a bit too far), to absurdly conservative (pretty much all of Europe after the fall of the Roman empire, for example), back to liberal, back to extreme conservatism.

And the amazing thing is that everyone, all these movements, from the puritans to today's women empowerment warriors, from the Roman Empire to Washington to Lichtenstein's government, see themselves as the first ones ever to do X, constantly, all the time, when in reality it seems to be a cycle that rotates around in about 1.5 to 2 centuries or so. And one the one hand that's true : there's something unique about almost everything, every movement. But 99% of what such movements stand for are duplicates of their former selves. It's just that the people in them are not at all aware of any of it.

Say, society moving away from the Church was of course, according to those who did it, the first time ever this happened (not what had happened ~80 times before, almost always in times of large economic expansion). They were smarter than everyone and "reason" was going to save the world (mostly because it had a few successes). If you go back to the time of the French revolution, of course, you'd see that the same happened, and then ... the great economy faltered ... and despite all the reason in the world (note: governments "based on reason" can easily match governments based on faith in cruelty and pettiness. In fact I would say that despite the general feeling the reason "based" governments are the worse ones. And yes, by that I mean that in times of economic desperation they're worse, far worse in fact, than things like the inquisition).

But no, the generations of the 1990s and 2000s are utterly convinced they are the first ones to ever see "the church for what it is", and that they'll just make the economy perfect and everyone happy and all will be well, because science and reason will save us all.

And when listening to grandpa you realize that the 1920s were just like that ... and the 1960s. And the 1930s and 1970s-80s ? Oh well. But those were smaller cycles, sooner or later a big shift will hit us again. It's been a while.

Coming up next: nope ... science and reason do not in fact guarantee a nice economy, do not in fact save us all. There was a nice economy, for reasons independent of religion, tolerance and this period will end, just like all other periods before it and people will flee back to faith, extreme conservatism, just like they've done so many times before.
