Education is an odd profession. Where people feel because they have had an education they are qualified to determine best practice. It is as if having an operation makes one feel as they understand the best practice in heart surgery. Teachers spend years studying teaching practice, always read the research on best practices, spend all day working in education settings. Yet people often dismiss their methods and demand change based on often misremembered anecdotes of their own youth over half a century beforehand and pride in their children. I wouldn't be shocked if a vast majority of parents thought their kids were above average, which isn't a bad thing, but sometimes professionals know what they are doing.
Teachers also operate under different constraints. Class sizes and number of classes per teacher varies, but a given teacher could easily have over 100 students. They also see those students for only a year before getting a new cohort to learn.
In contrast, parents have only a handful of children who they typically know from birth.
Not only does a parent have far more specialized insight into their child, but (perhaps more importantly) that parent does not need to make sacrifices for the greater good of the class.
Schools aversion to children getting ahead is largely duevto the practical challenges it imposes on the school system, not the pedalogical effects on a given child.
You do however spend probably 8 hrs working on it, read hackernews on latest tech, probably better than you were 5 years ago. Now imagine your marketing department saying they went to a computer summer camp once in the 90s and therefore think you should rewrite the tech stack in perl.
