Asians are now the highest immigrant group entering the United States. Immigration from Mexico is currently near or at net zero due to as many people moving there from here as here to there now due to the sluggish economy, however the Asians have not stopped coming (not that they should!).
In 2010 430k immigrants into the United States were Asian, that is 36%, compared to 31% Hispanics.
A major reason that Asians are coming and Hispanics are leaving is because the United States is and has been changing economically from a manufacturer to a technology provider.
Another major reason is that Asians who come with half a million dollars to invest into a tech company magically have their immigration process considerably less lengthy.
There then there are the many foreign exchange students to really enjoy the United States and decide to make families here.
In 2010:
45% of all engineering PhDs went to Asians.
38% of all Math and Computer Science PhDs went to Asians.
33% of all Physical Science PhDs went to Asians.
70% of all Indian-American adults have at least a bachelors degree.
49% of all Asian-American adults have at least a bachelors degree.
28% of all Americans have a bachelors degree.
Asians have a cultural emphasis on the importance of education. Their families spend a lot on it, their communities spend a lot on it, they invest for long-term prosperity through education when all over the United States most families and communities are devoting less time and energy to education. School districts fail funding levies every year and now we only have a quarter of American adults holding a bachelors degree, and that is with the Asian-Americans dragging up the mean.
Ladies and Gentlemen, we have our winners.
Bow to your new masters
