It is when you don’t go to the good schools, it depends almost entirely on your economic class. The better the area you live in, the better public schools tend to be or you’re more likely to be able to afford a private school where they actually educate you. My wife went to a super ghetto high school and they didn’t teach those kids shit except to shut up and do what your authority figures tell you to do, and pretty much everyone I’ve known from poorer areas had about the same experience. In America you’re not likely to get a real education unless you or your local taxes can pay for it.
