Is it what we haven't learned, or what we've forgotten? I was taught a lot of history in high school, but like most things that don't get recalled very often, I've forgotten a lot. Is that really the problem? Perhaps we don't reference history enough in modern society. On the other hand, I have a lot of knowledge of topics that didn't exist back in a time when people were supposedly more historically literate.
