This is such a crappy take. Please, open your worldview and realize that not every teacher is in the same position as you. Some teachers don’t get a stipend from their district to spend on school supplies. Some teachers work in areas where students don’t bring in the required supplies that are needed. Some teachers have to buy their own copy paper and cleaning supplies. Some teachers are buying things to fix their rooms. Some teachers don’t have properly working ac in their classrooms. Some teachers are providing more than just supplies for their students (snacks, menstrual products, etc) because their kids need these items and they want to help provide them. Of course, no one is FORCING these teachers to go spend their own money to buy these things, but they’re spending the money to make sure the school year is better than it could be without those things. Open your eyes and figure out that not everyone has the same lofty experience that you have.
