Schools shouldn’t be treated as these magical places where you’re put in at some age and over a decade later you emerge a complete human being. You have parents and you spend more time at home than at school for a reason: you’re supposed to learn from your parents.
A school can potentially give you a degree of financial literacy instruction. Your parents should be the ones paying your allowance money and driving you to the bank to get your first checking account. A school can teach you how to cook something. Your parents should be the ones eating your food and helping you cook it better. A school can show you some level of DIY. Your parents should directly benefit from teaching you how to fix the sink when it gets clogged. A school can tell you what kinds of careers exist. Your parents should love you enough to tell you that either your career ambitions or your financial expectations need to change. A school can tell you how to build a resume. Your parents should be the ones driving you to your job interview and to your job until you buy your first car. A school can give you a failing grade when you do poorly on a test. Your parents should be able to make you face the real, in-the-moment consequences of doing something wrong.
Expecting a school, public or private, to teach you everything you need to know is a grave mistake. You need people in your corner who are taking an active part in raising you all the way to adulthood and beyond. If you have kids yourself, that goes for them as well. If you aren’t there for your children, to teach them the things that schools don’t teach because they can’t mass produce the lessons to nearly the same quality that you can give them, they’ll blame you and the school for having failed them. And they’d be right to lay the blame at your feet.
There are no prerequisites for being a parent. There are MANY prerequisites for being a teacher. We should be fortifying the curriculum of our schools to give ALL students a good education, not allowing the birth lottery have as drastic of an effect on children as it currently does. Parents can be very helpful or nearly useless and schools should do their to help students recover from the failures of bad/unprepared parents
At the same time, parents should teach/reinforce all the lessons they think are critical, and not depend on an imperfect school system to do right by their child. If it’s something your kid should know and be familiar with, teach it to them. If they already know about it from school, find out what they were taught and be careful to consider what’s wrong and what’s simply different from when you were taught it.
Kids should have no expectation on who should teach them what. They don’t really have a say in the matter, they’re children. Everyone responsible for those children needs to do everything they can to make sure the children get a fair shot once they start having a little more control over their own lives.
