I think so much time is spent on things like the Roman Empire that we never get to details like “the reason the top half of the glass windows in this very classroom swing down and the radiators are hotter than the sun is so that they could ventilate all winter when respiratory diseases were at their peak.”

The problem is that certain people don't care if "others" are getting polio because it's not happening to them

They lack empathy, or even the basic understanding that helping the lowest in society almost always pays dividends.
