This is probably going to trigger some frothing but here goes: immigrants, and even more so their children, don’t know what it’s like to grow up “at home”. They don’t have the luxury of feeling everything’s going to be ok like it was for my great-grandpa, this is my world, these are my people, I’m fine just the way I am however that is. They can’t think that they have an innate right to anything (even if they have legal and moral rights). They can’t think “take me as I am, I’m just as good as you, take me or leave me”. They are always different, always on the outside, never know the luxury of not having to justify yourself - because they’re never “at home”. They simply don’t have the luxury of a mindset that allows for a “teachers can’t tell you what to do, if they do you just tell me and I’ll tell them where to go”. They know what would happen if they did.
They need to build a foundation and history for themselves. And, as has been said many times already, they need to work twice as hard to get half as far. Nobody who goes through that remains unaffected. It gets passed down the generations, especially given how little changes in terms of racism. In times of paucity/austerity, resources are spread even more thinly and the lowest rung sinks even lower and the fighting gets more vicious. So, they work. They push hard, just to stay standing.
I will never forget the day my opposite neighbour, an Asian eye surgeon in his 50s back then, was spat at by a white yob and called the n-word because he dared toot his horn to get the yob to move from where he was parked in front of his dropped kerb. I was a young girl and it’s stuck with me ever since. The sheer entitlement of that yob, in the face of a highly educated Moorfields doctor twice his age. All he had to do was throw his whiteness in this neighbour’s face. All that education and achievement still didn’t protect him from such disgusting treatment. Of course he pushed his boys hard at school and university (yes they’re both doctors). If an oik like that can get away with such behaviour, what are your options?
Immigrants generally NEED to work that much harder for stability and security. It’s not a given. That insecurity is inside you all the time, because you’re living outside your home all the time. It’s nothing special to the U.K. or the US.
