Latinos in Florida = lots of Cubans that were the elite (doctors, lawyers, landowners etc) back home. They gave up their position among The 1% to escape Castro since he wasn't having it.
Asians are tricky because you've got Hmong/Laotians grouped with Samoans, Koreans, Pakistanis etc. Some Asian groups do really well, while others struggle. I know Indians make the most money and Filipinos make quite a bit from being nurses and phlebotomists etc. Academically, I bet Indians >> Chinese/Korean/Japanese but it's close.
Black kids? It's not innate ability. What trips our kids up is a lack of preparation. We send our kids to school and expect the teachers to give them everything. Your kid should know how to read and have some degree of comprehension, do some basic arithmetic etc
I remember too many times in class. There would always be the loud/disruptive Black kid that will be the first to tell everyone "Tamika breaff stank" and point and laugh....but be struggling to read some basic azz sentences in a book. Shyt was embarrassing. How you gon run your mouth 24/7, always finding time to clown on people.....but you can barely read a page of an age-appropriate book?
