"I have said publicly before and I say it before this group today: As I look at the new generation of Americans of which you are, of course, outstanding examples or you would not have been selected for this program, it is the best educated new generation we have had--young generation; but more than that, it is the most involved, involved in the sense of being interested, not only in how you can get out and make a living, which was our primary concern in the 1930's when making a living was necessary in order to just keep going, but involved in the problems of your neighborhoods and the problems of your Nation and the problems of the world. Finally, it is a generation which knows more about the problems of the world and knows more about the problems of this country than has any generation in history. What this means is, very simply, that you are a political force, even though you do not yet have the right to vote. You will soon have it, of course. I say you will soon have it because you will be 21, or you will soon have it if you are from Kentucky because you will vote when you are 18. Of course, at some time there will be a constitutional amendment. I have noted that this particular organization, among many others, has indicated its support of that kind of a constitutional amendment."
