I don't know the exact answers to the specific questions you ask but I look at history and see the exact same criticism I have of Jews in the writings of great men like Christ, Tacitus, Seneca and Roman emperors long before the Ashkenazi even existed. I mean you can look at the story of Joseph in the Bible and his actions in Egypt and what exactly is the difference between his actions and the Rothschild family?

This is how they've behaved for thousands of years and it didn't suddenly start when some Turkic people converted to Judaism in the 9th century. It's a false explanation and actually I think a self-serving one given a Communist Jew Koestler himself was the first major proponent of the idea. It lets them off the hook.

That's what I find so absurd about the whole Khazar theory given that this negative anti-social and destructive behaviour predates the beginning of the Khazar empire by over a thousand years.
