Slave labor in early American paleontology is definitely not a topic that’s been explored a lot. People may “know” it existed, but there are always more stories to tell. That’s the great thing about historical research.

You'd be surprised what people aren't aware of or what they default to societal biases on if not clearly informed. Also, having a general inkling about slavery being used versus having a story/article/documentary clearly describe, model and expand upon its use will result into two different levels of an informed population.

Children don't if they are not told. I don't know how old you are, or if you have kids, but at my age, almost 50, and having kids; You get a weird perspective of how youngster don't know anything they aren't told, and that once you die, you will be forgotten quickly, along with everything you know. Social narratives only live a short time as truths, real quick the change and become something different.
