Yesterday I talked to someone who said they could do maths in their head.
I can too, it depends what kind of maths. We do a lot math in our heads anyway, including the thinking part.
So like give them a maths problem and they solve it in 30 seconds.
I doubt a real math problem can be solved in 30 seconds. You are being told elitist stuff by someone who is really being elitist, but not real. That said I do believe there are people who can construct equations and solve equations in their heads, but whether that is useful depends.
His teachers in high school complained he was not "showing his work".
Teachers usually have one way of seeing teaching, a teacher has been taught a certain schema and they follow it, because that is the only way they know how to teach.
So his mother was called, she said to the teacher if the teacher could not solve it that fast then the teacher was wasting her time, she needed to be at work in 2 minutes.
Mothers and fathers are bad at assessing problems when it comes to school stuff. They are concerned about well being of children, but rarely know what is good for their kids. That would require mothers and fathers to spend time with their kids. Most mothers and fathers don't spend much time with kids, if they do they rarely know what their kids are about. That goes for a lot of teachers and counselors too.
It is not a matter of schools being elite, it is a matter of if you are elite yourself.
Elite is subjective. What is elite in one way, can be detrimental in other way. Skills can be really advanced, but does not mean they necessarily translate to real world, cause that is the only way money is made ergo profit, and ergo product.
Schools want to see that students can produce something, because that means you get a job.
Elite people do things fast, so that is what the schools are looking for.
Sure, but not many employers necessarily are looking for show of skills. If I were business person I want to know if the person I hire will solve my problem. I would probably rely on the fact the person has a school, but realistically I won't know if they can do it, until they have done it. Schools kind of low level standard proof they can do something. Elite means you can do something above average, but life is full of elite people. Anyone dedicated to something above average is elite by default.
That is how the school system has been set up since the 1950s
In 50s kids were taught tangible skills, not just abstract stuff.
So if you were a kid in 50s you probably know how a circuit board looks like you probably know how to set up a circuit with a batter and a light bulb.
How many kids today actually learn in lets say 5th grade class how to set up a light bulb and a batter and make it work?
Kids in the past also made experiments.
I made a steam engine in 4th grade. I also made a cola drink. These experiments are rare though in todays schools. You barely do anything pragmatic and tangible today.
You are taught in the abstract. So much so you have highlevel skills, but you cannot even fix a sink or a trash can hing, or fix your own electric in the house.
These skills are basic, and even kids know how to learn these things, but today in the 2000s you barely know how anything works, despite that we are taught highlevel knowledge.
We have very uneven profile of intellect today. Very concept driven, but pragmatically 0 know how. This is because schools follow the trend of jobs on the market, but they don't necessarily follow any inherent logic or even common sense.
