It is remarkable to me how the education system has conditioned educators, at least in the US to either not ask at all (and really rightfully demand) or consistently ask for too little when we do ask.
We need to look no further than classroom supplies, and how the system has helped internalize that teachers should spend their own money to provide basic things that in literally every other field and industry are provided, like pencils and pens.
We really need to make more concerted efforts about this and call out schools and policymakers. When schools are out of paper it should not be teachers' responsibility to buy some.
