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.
Schools are sabotaged. They underfund the actual school so they can’t afford common supplies like this, or repair their AC or building upkeep, etc. They vastly underpay teachers so there are fewer of them, increasing workload per teacher so there’s more burnout and less effective teaching. They make wedge issues like the book bans, sex ed and anti-trans bills that prevent teachers teaching the obvious reality in order to increase anger at teachers to burn more out. They pass bills that allow people to take their taxes out of schools to move to other schools in richer areas or to keep if they homeschool (to indoctrinate).
They are the US republicans and the purpose of this is to ensure the most amount of poorer people are uneducated, don’t get a chance to get higher education. Which leads to ensuring fewer have well-paying jobs, and more people live desperately and can’t quit their jobs, move or exercise their right to assembly. This ensures a life-long near-slave caste of workers so billionaires have cheap labor and who are easily manipulated emotionally through fear keeping Republicans in power.
