Basic maths computational skills frees up time to tackle more complex problems. It’s nothing more and nothing less. Perhaps as gifted person this was never an issue for you.
It’s not about being better or smarter, it’s about people who felt they had to achieve more to be able to compete on an uneven playing field. It may be less of an issue now but for a generation of people who know they were blocked from access to opportunity due to their origins it is extremely important to make sure their kids are given a fair crack.
You fundamentally misunderstand the motivation for this. You believe it is about status and it’s actually about security. Asian people make jokes about it and their pushy parents but it’s driven by that. They don’t want their kids to struggle, they want them to to have choices, be financially independent be competent adults. Many immigrant families did struggle, starting from scratch, no inheritances, etc, in fact often supporting extended family.
I don’t see what’s terrible about wanting more for your own children.
