No it isn't. Being able to impregnate a woman or give birth does NOT magically make you a great teacher! My mother has an innate gift for teaching, and she STILL benefited from 4-6 years of college courses and continual training and improvement over the 30 years she taught and is still teaching.
Meanwhile, the entire time she has taught, parents have done everything they can to shift blame from bad home life and kids that don't value education to "you aren't doing enough" even as she literally buys her students winter coats, from her own pocketbook, as the school doesn't even buy her new markers for her whiteboard or new material so she can stop using 25 year old VHS tapes that are literally losing their contents from normal wear, even as she is one of the favorite teachers in the entire school system because of her immense empathy, even as "bad kids" do very well in her class because of how sincere she is, how much she cares, and how good she is at her job.
People say "We've increased so much what money we give to schools" completely ignoring that the money has NOT been distributed in any sort of even way, and even in my state which has largely good outcomes for education, the vast majority of the funding goes to a couple prestige schools in the south that were already rich because they are in rich towns, and the little money that trickles to the impoverished schools in the rest of the state largely goes to paying administrators led by superintendents that are just whoever the "Good old boys" were twenty years ago. Actual teacher pay has not kept up with inflation.
I'm so sick of all this teacher blaming bullshit around education. Actually trained teachers have been shouting about what they need to improve things for decades, and none of the managerial class has given them even a shred of what they actually need, while everyone continues to blame them, and have even claimed public education is just indoctrination. It's infuriating.
Education is a skill, a professional and knowledge based skill. Teachers aren't baby sitters, and if you decide you only need a high school degree to teach, don't be surprised when it goes poorly.
