I was a high-achieving student - mixed-race (part Asian). It's not as cut and dried as some of the stereotypical explanations.
Asian parents pushing their kids academically is definitely true. I actually don't know a single chld of Asian immigrants (across the UK, US and Canada!) who wasn't expected to get top marks. I didn't have nearly as bad a tiger mum as some others I know but helpfully for my parents all the expectations and pressure came from within by the time I was 11 anyway.
Maybe you can ascribe that to "culture" but in an immigrant context there's also the fact that I knew I needed to get top marks, not mid-range marks, in order to be taken half as seriously as my white peers. Getting top marks was my only hope of getting away from where I grew up and making the life I wanted for myself. "You need to work twice as hard to be taken half as seriously" is a lesson every non-white child in this country knows; it's hammered home by their parents and even if that doesn't sink in, life will swiftly let you know about it.
Having said all the above I don't think any of that is healthy. Asian kids who aren't naturally academic go through hell failing to live up to expectations, and woe betide them if they decide that they want to do something artistic or vocational with their life (which I eventually did). The happiness of the child and respect for them as an individual doesn't factor into any of the above (or at least it's framed as future happiness, dependent only on a stable high income). Being motivated by unfair treatment isn't healthy either, it's an indictment of racism in British society and I'd rather I hadn't been shaped by that.
In terms of whether you white parents can learn anything from it? It's a mix of you can't and you shouldn't. You can't replicate the lack of privilege non-white immigrants have - your kids will be able to coast and still succeed in a way we can't. You should enjoy that, because I always envied it. And if you'd rather your child was happy than high-earning or high-achieving, I envy that even more.
Unsurprising plot twist is that I'm NC with my parents, and much of the above is to blame.
