What were the Jews chosen to do? Christians believe the people were chosen to produce the Messiah and to hold the record of G-D's deeds among these people. A master race is built upon the idea of an ideal or super man who is better than the rest. The Jews are no better than anyone else, Jews are just blessed for keeping the records and following them. The long lived Rebbe are a testamony to this whereas those Jews who reject the Torah in favor of pleasure don't last any longer than anyone else.
