Interesting, but that case was closed by Mark Twain in his Essay, “Concerning the Jews”. Anyone interested in the topic should read it. Its the definitive explanation.

A few things I’d disagree with, Joseph wasn’t accruing wealth for himself, his status was a reflection of Pharaoh. And he clearly overestimates the number of Jews in many nations, but in those days how do you count those things. It’s an excellent analysis, far ahead of the “civility” of the 20th century.
As an Israeli, this made me laugh:
“Speaking of concentration, Dr. Herzl has a clear insight into the value of that. Have you heard of his plan? He wishes to gather the Jews of the world together in Palestine, with a government of their own ..... I am not objecting; but if that concentration of the cunningest brains in the world were going to be made in a free country (bar Scotland), I think it would be politic to stop it. It will not be well to let the race find out its strength. If the horses knew theirs, we should not ride any more.”
