I, too, like Calvin Coolidge--the last president to see himself as a chief magistrate as opposed to an elected king.
Calvin Coolidge. Absolutely. He was the one who said
that he was proud of his administration mainly because
he minded his own business.
CC undoubtedly understood and respected economic principles better than any president before or since. If the Republican Party had begged him to run again in 1928, the phrases "The Crash of 1929" and "The Great Depression" most likely would never have entered into the world's vocabulary. That could have made all the difference in the 20th Century. Might have been a lot different.
