Yes, I know. I was expanding on that about teacher-student ratio.
My mom was a teacher in a lower middle class/working poor area and we'd have discussions about what stuff she'd get and the rich kids in the district would get. I'm well aware. The rich kids got tablets and such, the other kids got outdated biology textbooks that had a very early grasp of HIV, for example.
When I was in HS 20 years ago, in the poorer schools they were still using textbooks from the early 80s.
When my mom retired in 2014, they were using textbooks from the mid-90s.
I don't have firsthand experience anymore but it seems like the kids from the lower class schools get the rich school's hand-me-downs.
Also, besides the info, wealthier areas would have 20 kids in a class, while others would get 40+.
