The whole educational system in this country is a very sick joke. Honestly, I never once used calculus in my 40+ some years in the workforce. What I could have used was some good technical training which would have made me an even better mechanic than I am (and I’m pretty darn good.)
George Carlin said it best. They don’t want people to be educated because if they were, they would know how badly they are getting screwed. What they want is people just smart enough to know how to push the buttons and run the machines, but not smart enough to know how badly they are getting screwed.
A good educational system would find out what the interests and strengths of a particular student are and then direct the education in that area. Interested in being a doctor? Biology, anatomy, sciences. Interested in being an auto mechanic? Basic mechanical skills and training in electronics and electricity. Some chemistry thrown in because of all the chemicals we use in cars.
And notice that no schools are teaching things like life-sciences: raising crops, animal husbandry, etc. That’s because The System does not want people who are self-sufficient and do not need our lying crop of politicians. Self-reliant people are strong people, that is something dictators hate with a passion.
