I didn't get the best education in public school - though I made up for it in college - but I did grow up with friends in vastly-different socioeconomic status than my own. There's a tragedy of the commons here: parents who can afford private schools and tutors for their kids set them up for more success, but it also saps funding for public schools and families that can't afford that. (Public education would be better funded and higher quality if rich families had a reason to care.) Basically, white flight, though more tilted towards class now than race. I want to send my kids to public school, but I know my individual actions wouldn't do much to fix the inequality.
