I’ve also seen US teachers spending hundreds of dollars out of their own pockets to stock classrooms.
I spent a lot of time in European schools and I’ve never heard of teachers having to stock their own classrooms or fundraise for things like playgrounds, etc.
Money doesn’t fix everything. It goes a long way in elementary school, but I went to a high school that had far more funding and tech than it needed yet underperformed because the students were horrible people.
