Not that it should matter to us Americans, but class consciousness is hardly dead in England, and mere money does not equal status. Some of the ancient families have land and money, some, especially in the gentry, where one finds most of the really old families, don't have very much, but all are well-known in Society in England and will be received if the go up to London for the Season. Jews, even very rich Jews, even Jewish peers, still generally are not received in the upper reaches of Society in England. I have had occasion over the past 40 years to make acquaintances among several of the European upper classes/aristocracies. Though not a Jew, as an historian, I have always been interested in the phenomenon of antisemitism and have listed with a close ear. In my experience, anecdotal as it is, the least antisemitic aristocrats are middle levels (barons and counts) of the German aristocracy (but not the Austrian) and the Italian aristocracy generally. The French, especially graduates of the Ecole Normal Superior, but less so graduates of the Ecole Polytechnique are the worst, followed by the Scandinavians (only the Swedes and Danes still have an aristocarcy, the Norwegians an upper class) and the British.
Suffice it to say that while public discussion of the Jewish Question has been taboo from 1945 until recently, it has always been known among the more intellectually minded circles of the upper reaches of European Society.
