What if a teacher just refused to buy classroom supplies with their own money?

65. I could not find recent information. My computer is too slow, doesn't mean it isn't available.

But here are the statistics from 2009.

Of the meals served daily, approximately 78 percent of students in the LAUSD qualify for free and reduced-priced meals. Meanwhile, the number of students who are eligible for the subsidized meals is growing as parents lose jobs or have their hours cut at work, and more families become homeless. While there is a decline in student enrollment, the District has served more than 10 million additional meals in the last two years.

That figure should be lower today, but not that much lower. Even if it is "only" 50 or 40% today, that demonstrates how great the need is for teachers to buy supplies for their classrooms, especially study aids.
