@cicerone imposter,
C.I., Asians weren't brought to this country in chains, kept in bondage, bought and sold as livestock, not regarded as full equal citizens, then relegated to totally segregated facilities in housing, education, etc in the South, as well as de facto segregation in the North. This country, and it's black population, still bears the scars and legacy of slavery and racism. We've made strides in the past 50 years, since Martin Luther King Jr's "I have a dream" speech, but 50 years isn't really that long a time, and the effects of history aren't erased that quickly.
Blacks who have come to this country freely, as true immigrants, and who continue to migrate here, generally manage to do very well, and they are more equivalent to other immigrant groups. But they also have the financial resources, and supports, that allow them to be able to come here in the first place.
The black young man, his son's friend, that Hawkeye referred to, might still be subjected to police stop and frisk tactics, suspicious looks, and even racial profiling by types like George Zimmerman, no matter what his accomplishments are.
