It's nice to dream about but it will never happen. The incentives are all wrong for public education to teach critical thought.
The politically appointed or "hired by reference" committees and/or teams of bureaucrat that are responsible for setting curriculum at the state level would never do that because then they'd have to answer to politicians on both sides of the isle for making their job harder. People operating at these levels of bureaucracy don't need to be told what the boss wants, they read the room and know in which direction they should be erring. Your career doesn't take you through those sorts of positions that far if you're not the kind of person who does that.
Furthermore, the career arc of someone who believes that society's problems will be solved or mitigated by helping the masses think critically is unlikely to take them anywhere near the high levels of public education policy.
And even if it did happen the schools wouldn't teach it and they'd have to be dragged kicking and screaming over a decades long period (because the unions and the municipalities have enough power to play that stalling game for that long) because corralling teenagers is harder when they can call you on your bullshit forcing you to address tough topics that have no good answer other than "I'm in charge, deal with it".
