Perhaps knowing all the math in the word wouldn't have saved them, but the math is inherent in a corrupt system which we all need to fight to change.

Not to push it too mucch, but this was the idea I hit upon in my book, so if you're looking for these sorts of stories you could do worse than start there: https://www.amazon.com/Math-Life-Death-Mathematical-Principles/dp/1982111879/ref=sr_1_fkmr0_1?crid=VWXFWH6IJA6W&keywords=the+maths+of+life+and+death+kit+yates&qid=1564181090&s=gateway&sprefix=the+math+of+life+and+death+%2Caps%2C120&sr=8-1-fkmr0
