> Access to education has been one of the best thing to happen to minorities, and Asians are a good example of that. Most came from poor immigrant families and in the space of 2 generations they made it to top universities. So what exactly were we doing wrong? Seems to me the system is clearly working as a social escalator.

The overarching theme is that non-asian minority populations may be disparately affected by adverse conditions continuously perpetuated on them such as single-parenting.

And before we conclude that single-parenting is the fault of the parent -- no, not generally. It's generally the fault of the society that disparately targets adults of a given background for separation or incarceration.

If we're being frank, neither white majority nor Asian minority populations have had to deal with imposed inadequacies in family structure.

TL;DR: Asian immigrants are more likely to have support networks similar to the majority population, something frequently deprived from other minority populations in the US.
