McGraw Hill wrote every textbook in my public school. Imagine that, a private company being able to control the narrative. We never learned about the soviet role in WW2 unless it was about the "endless hordes".

America was painted in the light of being europe's saviors against hitler, no mention of the fact that IBM pretty much orchestrated the holocaust. We also read plenty of books related to the holocaust, independent authors this time at least, but it was always about Jewish victims. Never a mention for any other victims, it wasn't until I was in college that I was told they targeted Romani's first, and it was mentioned off-hand since they did it to "clean the streets" before the Olympics (gee, I wonder what the California governor is doing right now?).
