Calm down man.
There are bad people among the Jews who are bankers but also good ones (such as Ben Bernanke who basically saved US economy in financial crisis from civil unrests by starting aggressive quantitative easinings).
There are a lot of non-Jews as banksters, too. I guess in Finland the majority of banksters are goyim and our economy still sucks as the governement is licking the asses of EU with the situation with Russia.

The money comes from the Creator. The Jews are the chosen people of God. This you can read from the book you call "Old Testament".
If God chooses a people He is not acting like a mortal human being by changing His mind every time something not nice happens.

What comes to your comment on killing jeshu (your later post), even the New testament tells it was not the Jews who killed but Roman soldiers (despite according to the Torah Jeshu deserved to die since he violated the commandment of Shabbath which is compulsory for the Jews).
