It's bullshyt to attribute that primarily to "cultural values around education", that's the same model minority BS used against Black communities all the time.
"Low-to-middle income" households from certain Asian immigrant communities do well because those are an extremely small and elite subset of their national population, mostly families that were either highly educated in their home nations, came to the USA via education visas, or are the rare highly entrepreneurial talents. The vast majority of disadvantaged poor in those nations ain't touching the USA, so trying to compare their most elite performers to the entire Black population, or especially Black folk in low-income communities, is bunk.
In the cases where Asians come to the USA via refugee status rather than high-skill visas and entrepreneurship, and thus the immigrant population is more representative of the entire nation (Laotians, Cambodians, Hmong, etc.), their academic and financial performance isn't any better than it is for Black folk.
Just look at India. They have a horrific education system, do poorly on every single measure of school performance and even basic IQ. Yet they are among the most elite in the USA, beating out nearly every other racial group. Where are those "cultural values" for education in their home country? Do Indians just magically change when they get to America? Hell no. It's that the 70% of Indian families in poverty with shyt educations can't dream of touching a US visa. Even the random Indian truck drivers and restaurant cooks in New York were part of the elite in their home countries and already have a huge head start in education and stability which they are then able to pass on to their children even if it didn't translate immediately into a high-paying US job for themselves.
