Old info but still massively superior to cherry-picked meme graphics.

Overall elite:

Wasps 43%

Other Protestants 19.5%

Irish Catholics 8.5%

Other Catholics 8.7%

Jews 11.3%

Minorities 3.9%

So we see that Jews are outnumbered by Catholics among American elites and are not massively higher than Irish-Americans alone - a traditionally fairly working class group.

There is more that I'll add but the source for it and what I'll add later is an article in the American Sociological Review from 1982 entitled "Ethnicity in the American Elite".
