On another thread I once stated that greed was in the hebrew DNA.
(Avarice would have been a better word to use)
If you read the Torah it says that Abraham was the wealthiest man of his time; same with Soloman, King David, and other chosen people notables. So yes, it is in their psyche, if not their biology
That being said, the Jews have a pejorative tendency to put themselves in societal positions to control their host nations money and economy.
It's been that way since Joseph was sold into slavey by his brothers and eventually ended up being Pharaohs head man in charge of Egypt's treasury.
And you can see that behavior right here in the U.S.
Just look at the last names of the heads of the top financial institutions or the heads of the Federal Reserve.
Anyway, once the "Chosen People" have an iron grip on their host nation's economy.
They start trying to destroy the customs and traditions of that nation to better position themselves. So they enter politics and the judicial system in order to help make the laws and give them even more power.
This behavior is easily evidenced right here in America. Just look at the leadership of any group advocating change of social morals and values; feminism, gay rights agenda, teachers unions, redefining marriage, etc. The heads of the advocating group or organization will most likely be a Jew.
This behavior follows the hebrew people no matter what country naively allows them to enter their land and set up shop.
After many years; eventually the indigenous people of the host country discover they are no longer in control of their nation, or their cultural destiny, and demand change. And drive the Jews out of their land. So the Jews seek another host country to give them refuge and start the process again.
This same senario has played out many times over many centuries..........
