The definitive difference between Christian and Jewish values is, as I see it, that Judaism does not treat wealth with shame. Indeed, nowhere in the bible does it say that wealth should be shameful. It is the application of wealth that is important.
Since Christian/Roman times, the Jewish faith allowed money-lending, where other faiths did not. Thus, the Jews forged ahead in the early banking industries, etc.
This shadow of history remains with the Jewish populaton today. The pogroms, which began in early medieval times, (perhaps before), occured when a King or wealthy baron owed too much to a Jewish family ... sometimes entire kingdoms were owed.
Such were the times, the Jewish money-lenders were slaughtered ... because it was far easier to do that than to pay the sum of money owed.
This mind-set/activity went on for generation to generation. The difference, anna, between the Christian and the Jew is purely a matter, (historically), of the application of money.
I doubt that much of Western Europe would have benefited without the Jewish input. But the money-lender is always vulnerable ..
