I understand now thanks. That point doesn't make sense to me in the context of the article because the article is claiming that black and Latino gifted children were under-scouted until the BLM movement. Seems that this and that are 2 different issues.

Prop 13 had a huge negative effect on quality of public schools in California, which I got to experience first hand.

The difference was quite apparent to me during high school when I compared my older siblings’ yearbooks to my experience of the same school a decade later. They had so many more classes, clubs, sports, programs, and activities available to them than I did.
