European class hierarchy contained anti-Jewish discrimination so it never became politically dangerous

Evidence

Social antipathy for Jews, with its varying forms of discrimination, did no great political harm in European countries, for genuine social and economic equality was never achieved. To all appearances new classes developed as groups to which one belonged by birth. There is no doubt that it was only in such a framework that society could suffer the Jews to establish themselves as a special clique. — Hannah Arendt, The Origins of Totalitarianism, 191
