"Don't Bite the Hand That's Feeding You," from 1915. Unfortunately, it is human nature to resent one's benefactors. Thank God dogs aren't like that.
It always seemed to me that new immigrants have a better chance of appreciating the uniqueness of America than do those of us who have been here for many generations and tend to be spoiled and to take it for granted. However, my family has been here since the 1600s, and I take this blessing not at all for granted. Freedom from the State (and my genes) are my most precious heritage.
