Precisely why the western ruling class don’t want their peasants learning maths, because maths also gives people the critical thinking and logical reasoning skills to see right through their idiotic bullshit.
It’s the same why the church fiercely resisted science during the dark ages, stupid people are easier to rule over as they can be easily brainwashed into thinking the least you can be bothered to do for them and provide for them is the best they can hope for (this is why American leaders are so obsessed with spamming the ‘greatest country on earth’ mantra, if America is the greatest, then be happy with what you got and don’t even fucking dream about asking for better!)
A well educated and critically thinking populous is so much harder to please and satisfy that ruling over them just feels way too much like actual hard work for the privileged western elite.
