Elite ethno-religious group: I run across bloggers all the time who are extremely interested in a small but very elite ethno-religious group. Even though they are a tiny sliver of the total American population, they are found in disproportionate numbers in the highest echelons of society.
Always interested in precision, I wanted to see what the General Social Survey (GSS) had to say about this group. Compared to all whites, they are three times as likely to be in the highest income bracket. They are four times as likely to hold the single-most prestigious job (according to the GSS) in America--an MD. Their rate of earning graduate degrees is 3 times that of the average.
More than 80% believe that America should take an active role in world affairs. Almost 90% believe we should stay in the UN. More than 80% believe that immigration improves American society, and almost 60% feel that we should either increase or maintain current levels of immigration.
For decades, this group has worked relentlessly to undermine traditional America with its liberal agenda: immigration rights, human rights, anti-racism and anti-Semitism, homosexual rights, affirmative action, economic justice, and feminism.
Oh, by the way, the group is the Episcopal Church of America. (Okay, maybe I cheated a bit on the "ethno" part, but it is true that the ancestors of half of the current members were from Great Britain (GSS)).
