Out of all the Barringtons, this is the most "new money" of them all. It also has the most wealthy Asians in Cook County and possibly the whole Chicago area. It seems like all the rich Asians from Schaumburg and Hoffman Estates are moving to South Barrington to get away from the Asians and Hispanics who are ONLY "upper-middle class".
Dude, have you been to South Barrington? It is so rich and unaffected by the recession that they might as well call it South Asia.
