I never said improve it. I'm against public education, at least for my kids. Everyone else is free to choose as they want, or don't.
Hey! Lot's of successful people haven't graduated from High School! My uncle immigrated from El Salvador, started out as a tradesman and now owns one of the most successful plumbing companies in Los Angeles.
Education isn't beneficial for everyone because people don't learn the same way. Not everyone is meant for college. Not everyone has the same goals. Do you want the state teaching your kids about slavery? About sex? About interpersonal relations while maintaining self respect? Come on, dude. Gimme a break.

You're not telling me that I'm supposed to explain these things to my own children, are you? I can explain why they shouldn't talk to strangers, why they should wash their hands, why they should be kind to people and animals, but forbid I ever tell them about Ess-Eee-Ecks.
The American Education system builds drones at best and trains prisoners at worst.

Why do you want the Government to educate YOUR kids?
