Not quite true; well some of it is but only in certain areas and yes Anti-semitism was rampant during this period. But what is important to realize that the reason why Jews became associated with certain professions - ie. Banking, certain types of small business - was due to the Catholic church's ban on Usury (ie. Lending money at interest) during the Middle ages, but as there was demand for a such service the biggest non-Catholic minority were those who were advantaged. This is where the whole "Jewish Bankers" stereotype (and not the only one) comes in.
Of course by the time of the Nazis; all that was only a truth in history. Only the Rothschilds (who weren't medevil) were left; didn't stop alot of anti-semitism spreading from generation to generation (as alot of anti-semitism, though not all of it - far from it, is often associated with a rejection of what can be seen as "urban values".)
All this does not o\c mean that DWDL is not a deluded plank who should move to somewhere East-St Louis pronto.
