In recent days, Jack Wertheimer and Steven Cohen have offered a salutary reminder that non-Orthodox American Jews are “standing on a demographic precipice.” And backing away from the cliff’s edge, they tell us, will require focusing squarely on the young. According to their prescription, a return to Jewish flourishing will be secured by stressing the importance of day schools, residential summer camps that offer “serious Jewish content,” Israel trips “for sixteen and seventeen year-olds,” youth groups, organized campus activities, and efforts to stimulate in-marriage or convert gentile partners. It is hard to dispute that these are top priority agenda items – as they have been for some time. And Wertheimer and Cohen are right to sound the alarm; with the ground moving fast under our feet, it is too late for complacency.
