It is hard to think of any work of art of which one can say 'this saved the life of one Jew, one Vietnamese, one Cambodian'. Specific books, perhaps; but as far as one can tell, no paintings or sculptures. The difference between us and the artists of the 1920's is that they they thought such a work of art could be made. Perhaps it was a certain naivete that made them think so. But it is certainly our loss that we cannot.
