I think unfortunately for multi-generational Americans there is a weird stigma when you come from certain backgrounds --some people escape them, but not most. Immigrants don't usually have this stigma and burden. They come for the opportunity which they believe comes with putting in hours or work and study. If you're second generation and greater, you assume many Americanisms like you're entitled to American things without the hard work. Immigrants are willing to sacrifice a generation so that the next might succeed. Quite a few of my HS cohort didn't have it in them to put in hard work. They wanted to hang out, play, skip school, go to the mall, smoke weed, get beer, etc. Kids of recent immigrants were not like that, by and large.
They would be foolish to value those things when they can look around the world at large and see how success vs failure is pretty much some combination of luck and network/nepotism.
While I’m not advocating the Chinese entrance exam system, we’re the polar opposite where being lazy is cool. Look at all the youth drifting to LA dreaming of making it big. Some of that is going to YouTube/Instagram type platforms but it’s still a one in a million shot at glamorous success rather than steadfast hard work for a steady career (we do have physicians and lawyers and MBAs who resemble the steadfast attitude but it’s a small slice of society) we’re just not good at instilling this culture in our youth as well as other cultures do.
These kinds of problems get inherited from generation to generation, even if (a damn big if) the current generation were not directly subjected to any of the original racist cases thereof.
