It is not a miracle. Indians immigrating to US are more educated than the general US population [1] (40.6% have graduate degree, 32.3% have bachelor's).
Have you also thought about why Indian American kids win spelling bee's or Jews win Nobel Prize disproportionately when compared to their population?
Comparing Indians or Asians to blacks is not fair. They are mostly recent immigrants (except few brought in as labourers) and did not have to suffer through the horrors of slavery which left blacks with broken family structure and other things (It is complex, like housing seggregation where the black neighbourhoods did not increase in wealth when compared to white neighbourhoods, criminal justice system)
