Well it's easier for me to say, having grown up relatively poor in a relatively poor area. The kids who listened, took notes, participated, for the most part all did well in school and went off to college. Most kids did not, they were disruptive, asleep, rude, violent, etc. Public school was very frustrating to me for that reason, so I guess it struck a nerve.
The equity vs equality is hard to square. Imagine someone who came from real poverty who worked 2 jobs while studying to give his family a better life. He or she makes it, finally, only for them and their kids to be punished for it come admissions time. Is that fair? I don't have great answers, I just feel like everything they try today isn't right, either.
