While it's true that there are differences, I think one lesson we should learn from history is that that virtually every group thinks they're especially unusual and that lessons don't apply to them, and simultaneously that they're usually not so unique as they think, and the lessons usually do apply to them.

School was less common at that time, but plenty of people went to school, and if there was a marked dropoff in employablility even in just that group, it should absolutely be visible.
