My civics and history teachers ware more subtle. Occasional mentions of a news article about some welfare queen, how great Disney was for Times Square, how great it is to be invaded by America(Japan was their only example), or how the Walton heirs were the richest people behind Bill Gates(they weren’t). I think one of the biggest Aged Like Milk comments was how real estate was such a great and sound investment. This was around 2003.
Meanwhile, I only heard one mention of climate change from the science teachers in those four years. I think the biggest lesson I got from school was to never trust authority and always press for sources.
