If one is to consider "Jewishness" to be global managerialism, then historically-speaking, we Europeans were the greatest Jews.
I suppose the key difference however is that while the European was actually a productive and creative race that brightened the world with art, technology, and in general everything that is to be thought of as culture (and as such are revered as 'bringers of light' or other such sentiments), the Jew on the other hand simply aspires to be a vampiric excel spreadsheet over the world, with his usury, with his Talmudic ideology of take take take from their slaves, with their mathematical manipulation, with their tedious dialectic chicanery.
At least, from my worldview which was influenced from everything from the classics of the 19th century in antisemitic works to the thoughts of the 20th century until 1945 when antisemitism became thoughtcrime, those are my perceptions.
It's rather sad that such great minds like Spengler dismissed these aspects of antisemitism wholesale. He did great work in his books, including his magnum opus Decline of the West, but for him to negate antisemitism as mere 'envy' was a credit against everything he wrote. This man, who claimed his most influential pillars of Goethe and Nietzsche, wouldn't have agreed with him.
Nietzsche, in fact, said nothing is more reprehensible than the modern "stock exchange Jew." He shared my sentiment, that while there could be an admiration of the Jewish race to achieve power at all costs – even "winning ugly" as was the title ironically of a book by a Jew tennis coach Brad Gilbert – Nietzsche lived his life torn between many ideals, and more than that he never wanted to be an absolutist, but to argue from every position to suss out the weakspots, to make himself and his readers stronger, even if this meant taking the side of the Jew at times for any possible beauty they might have, and in his opinion, all they had was a vigor to dominate.
At least in the end he conceded that their methods of domination (the stock exchange Jew, this modern manipulator of math and mouth-breathing) are as beautiful as the domination of some town rapist with STD's infecting all of the little girls. Sure, he has power as a rapist, sure he has power to his ends of his own amusement of raping and giving STD's, but who he rapes and who he gives STD's to (and whoever cares about them), should they not recognize it and fight back with everything, then in Nietzsche's opinion they deserve to get raped and get STD's.
In other words, a just society arrests and locks up that person, who I've used as a euphemism for the Jew. Our society of sick confused weaklings thinks the Wall Street Jew is just fine, they think "good for him, he's earned it, you're just jealous you can't do the same! You wish you were clever enough to pull off a credit default swap swindle!"
It's quite sad that Spengler fell in this trap.
