Here is Calvin Coolidge, from his 1923 Thanksgiving Day proclamation. He wrote this himself, as he did all his speeches.
The American people, from their earliest days, have observed the wise custom of acknowledging each year the bounty with which divine Providence has favored them. In the beginnings, this acknowledgment was a voluntary return of thanks by the community for the fruitfulness of the harvest. Though our mode of life has greatly changed, this custom has always survived. It has made thanksgiving day not only one of the oldest but one of the most characteristic observances of our country. On that day, in home and church, in family and in public gatherings, the whole nation has for generations paid the tribute due from grateful hearts for blessings bestowed.
To center our thought in this way upon the favor which we have been shown has been altogether wise and desirable. It has given opportunity justly to balance the good and the evil which we have experienced. In that we have never failed to find reasons for being grateful to God for a generous preponderance of the good. Even in the least propitious times, a broad contemplation of our whole position has never failed to disclose overwhelming reasons for thankfulness. Thus viewing our situation, we have found warrant for a more hopeful and confident attitude toward the future.
In this current year, we now approach the time which has been accepted by custom as most fitting for the calm survey of our estate and the return of thanks. We shall the more keenly realize our good fortune, if we will, in deep sincerity, give to it due thought, and more especially, if we will compare it with that of any other community in the world.
… We have been blessed with much of material prosperity. We shall be better able to appreciate it if we remember the privations others have suffered, and we shall be the more worthy of it if we use it for their relief. We will do well then to render thanks for the good that has come to us, and show by our actions that we have become stronger, wiser, and truer by the chastenings which have been imposed upon us. We will thus prepare ourselves for the part we must take in a world which forever needs the full measure of service. We have been a most favored people. We ought to be a most generous people. We have been a most blessed people. We ought to be a most thankful people.
Yes, we should.
