The hatred of the Jews has its roots in the blood libel and conspiracy theories but basically boils down to the hatred and suspicion of an "other." Successful Jews were doubly hated because it was evidence of the conspiracies: of course Jews couldn't become wealthy by being Fine Upstanding Germans like Hermann Schmitz.
The economic based hate came from the accusation that they Jews were stealing money from hard-working citizens. This belief was grounded in the fact that despite the depression followed by recession in the early 1930s that crippled the German economy, Jews were relatively well off financially. Because of this, Jews were seen as greedy money mongers who were obtaining their wealth illegally, even though their fortune came from the practice of money lending.
Many Germans believed (wrongly) that they were winning WW1, and should have continued to fight– that they were betrayed by their (allegedly socialist, allegedly anti-German) leaders in accepting the Treaty of Versailles. This is the Stab in the Back myth.
This was blamed on the "others" in society the above poster mentioned. In particular, the Jews– in part for their perceived connection with Bolshevism and with international finance, as you mentioned. They were thus the "other" on which the very exclusionary German conception of a "People's Community" was based!
So you're on to something, but as you suggested, the above poster is pretty right. Thanks for reading!
Personally, for some issues I feel it's important to be sure that we know what we are talking about.
Speculation can lead to widespread misunderstandings. That's no big deal when talking about the latest Chrome update, but it is for serious issues. And consider that in this case and in many others, so many people have suffered based on misunderstandings (sometimes deliberate ones) and people spreading them. For me, it makes a few hairs stand on end!
If success is defined as not working, but parasitically living off the labor time of those of us who do work, as heirs and VCs and their LPs do, then yes, there is a hatred of "success". We who work don't need heirs parasitically living off our work and sweat.
