So just by living like we do today with having opinions and voicing them you've already influenced your society back then. If you do the same today, nothing would've changed.
I also can't think of a time period or large geographic area that's had writing being common and most people were constrained to a society of 200 people, unless they were purposefully insular.
the usual town did house significantly less then a thousand people. compared to a usual town of today with >40k inhabitants.
the first industrialization started in the middle 18th century though, so not sure what your point is.
Heck, ancient Athens alone (a single Greek city) had a population in the "low thousands" in 500 B.C.
There was a Rome, and then a fall of Rome and the dark ages. And the same for tons of institutions, states, cultures, etc.
Heck, there was the pre-war Germany and then there was the Nazi germany.
"Kids these days" is often very true compared to what preceeding generations did at various times.
Past people were much more involved in societal change and day to day history than we are.
