Looking at the breakdown, then perhaps Indian mothers are the superior ones? :-)
The point is that optimizing along one or two metrics such as income or education is myopic (which was the actual topic of the article), especially when you don't take into consideration the associated costs (opportunity and otherwise).
Look, you asked for a citation and I spent, apparently wasted, my time getting you two. Looking at income, education, percentage of children born out of wedlock, incarceration rates, and a number of other metrics, those of asian are doing very well compared to whites, blacks, and latinos.
If you want to pick your pet metric and explain why asians actually aren't doing so well, then you should provide citations and make your case.
