The civil rights movement greatly helped jews.
Prior to the 1960’s there was much anti-semitism in the US. Jews were not allowed to live and go many places and religious liberty was not really tolerated.
After the civil rights movement , it became ok and differences were accepted. The laws not only prevented discrimation against race, but also creed. Laws were passed to mandate early friday leaving without penalty. Laws were passed that one could take off Yom Tov. Laws were passed that jews could get any job they wanted (Hollywood was mostly Jewish because that was one of the few jobs jews could get)
