What set of rules did you use to draw the line between an opportunity and an outcome there? Why does it stop at highschool, and not continue on to university, jobs, or board seats?

Because you might just as well frame public school as the government stepping in to mandate that there are seats in elementary and high school for everyone.

Everyone has access to public school (hopefully of decent quality). Not everyone learns the same amount. Not everyone gets A's. Even more, not everyone is valedictorian.
