A moving study of the problem of migratory labor in this country drew wide attention. This program moved many to express their concern to me in many ways. I was traveling in Wisconsin then. From the response in my State. I am sure that Americas heart was deeply moved by this great development. There have been programs on the U2 affair. on the sitins. on the world refugee problem. and on other subjects of equal importance. These programs have had an immense impact on tens of millions of Americans. providing a vast increase in understanding. I think that one must recognize that the television networks elbowroom is limited by certain factors.
