Second generation always have it easier but that wasn't at issue. Plus you can't take a genius and extrapolate it to an entire group. Hes no more analogous than saying LeBron is representative of all blacks.
The first generation indian came here with nothing. They passed things down and passed them on. More came because of demand for their labor but they didn't just waltz over.
On the whole, much worse off than blacks yet do much better. It's because their culture is about family, accountability, and hard work. They refused victim culture. You can look within each race, and people practicing these mantras are by and large successful.
Change the culture. Change the future.
