It's been case law since 1856 when SCOTUS ruled in South v. Maryland that Law Enforcement has no duty to protect individual citizens. You cannot sue the police for damages if you call them for help and they do not respond in time (or at all).
One of the more brutal examples of this is Warren V. District of Columbia.
The story of the plight of disarmed D.C. residents really begins on the night of March 16, 1975, when three women, sharing a townhouse, were awakened by the sound of their door being kicked in. This was no ordinary burglary or home invasion; this was a horrific, unspeakable crime.
Two of the three roommates had rooms upstairs. They were awakened by the screaming of their friend downstairs who was being beaten, raped and sodomized by two men.
Carolyn Warren called the police and was told help was on the way. She and her other upstairs roommate watched in horror as a police car passed their home, merely slowing down. They called the police a second time. This time, there was no response at all. After an hour, hearing no sounds from the floor below, they called down to their friend, but merely alerted the rapists to their presence.
After that, all three women were forced to endure 14 unspeakable hours of sexual torture.
In essence, the government, short of a "special duty" has zero obligation to come to your aid if you are in distress. This is why the importance of having the Right to use the tools you determine necessary to defend yourself (i.e., firearms) is absolutely critical. I also spoke on this in my article The 'Why' of the Second Amendment, Part 1.
Teachers (as government workers in the public school system) are under the same non-obligation. In June 2018, a Michigan judge ruled the state has no duty to provide literacy services to children. Judge says there's no fundamental right to learn to read and write. In the "'Why' of the 2nd Amendment" article, I stated that the deputy who waited outside of the school during the Parkland school shooting had no legal requirement to enter the building and engage the shooter. His obligation was to arrest the shooter and bring him to the prosecutors. The human thing to do would have been to charge in and engage the shooter, even at the risk of his own life.
The government has no obligation to educate you. I can't say that enough. George Carlin in a rare moment said (paraphrasing), "...[those in charge] want workers who are just smart enough to run the machines and do the paperwork but lack the critical thinking skills to see how bad things suck." The bad news is, the government pretty much is in charge of the People.
The decision to be literate is made by the person. No other person can force them to learn to read and write. Quite frankly, children can be taught by the parents that they don't need to learn these things, which is why if you read the article, you would find that only 44% of Detroit third-graders can read and write at their grade level. This just boggles my mind. I don't know if the parents don't care, if the children have learned helplessness from the parents and don't try, or the teachers are incompetent. Probably all three to varying degrees.
The advancement and enhancement of society in general depends on each citizen knowing as much as possible about a few things and being somewhat knowledgeable on many things. In my daily job, over 80% of my service calls are due to end-users not understanding the basics. They try to use equipment that clearly says "NOT IN SERVICE," or the screen is dark. They put documents into the wrong ports, the access cards they have to insert look like a Pringles chip and so on. One time a piece of equipment was getting removed from a site to allow for the installation of a newer unit. It was on the truck and ready to be hauled away and an end-user climbs up on the truck to use the old model. It had to be explained to the end-user that the unit on the truck would not work because it was not hooked to electrical power.
Common sense, the ability to acquire knowledge, to logically reason based on that knowledge and the ability to defend yourself are have to come from within yourself, through your own active efforts. If you let government give them to you, don't be surprised to find them not there to help you, or to be there to hurt you.
