Oh, boy!
First, I gather that Rick Sanchez is a television personality of some sort. I've never heard of him.
Second, in the early 1960s the U of Chicago hired Fr. Andrew Greeley, a Catholic priest who worked a lot with statistics. I took a class from him, and he was one of my three or four favorite teachers, mostly because he understood statistics. He also worked with the National Opinion Research Center, whom we lovingly referred to as "Nork". One of the things he worked on was analyzing the Irish-American immigrant community, sorting the differences among first and second generation Irish-Americans and sorting their differences from other groups. Most of the work was published in his book, A Most Distressful Nation.
When I hear stupid remarks like, "Jews own the media" or "Liberals own the media", I know two things: The person talking has shit for brains; and I don't care.
One of the things Greeley discovered was the "courthouse-to-white house" effect of ethnicity. Starting in the 1850s and 1860s Irish immigrants in large cities, mostly Boston and New York, became politically active. By 1880 most Northern city governments and police departments were majority Irish. By 1910 to 1920 many state governors were of Irish ancestry. In a survey done by Nork in 1960 of members of the U.S. foreign service career diplomats, 80% identified themselves as being of Irish ethnicity. And that year the first American of Irish ethnicity was elected president.
Electrical engineers? A few. Heart surgeons? A few. Airplane pilots? A few. Politicians? All over.
So was it a Celtic conspiracy? Hardly.
Between the creation of the U.S. Department of Agriculture and today, anybody want to look up how many Secretaries of Agriculture were of German ancestry?
