You can’t learn in high school what you can learn in college for two simple reasons: 1) there’s not enough time to learn it all, and 2) even if there was, the human brain does not work the same at 14 years old that it does at 18 years old.

And you don’t get an expansive view of human knowledge in “general studies courses,” you get it by taking a broad array of specialized courses. Again: takes time.

Trade schools are great for learning a trade but there is a lot more to life than a trade. There’s more to a society than who has a higher salary.
