The 1920s are the decade that signaled the arrival of a gift that still means a lot to us: Saturday.

Fame is worth less than service.

Coolidge liked the dignity of the presidency. He didn't get on the phone easily. It's possible that he banished the phone from his desk. He was known to use it from time to time. The person who was hilarious with the phone was Hoover. He was a real engineer. He made a closed circuit phone where he could call the important people and they could call him, a government hotline, but it was closed. He shut out the possibility of input from people he didn't expect to get input from.

If Coolidge were a stock, he'd be a buy. The experts have historically ranked Coolidge in the bottom quartile or bottom half of all presidents. But his economic performance and his statesmanship suggest Coolidge belongs in the top quarter of presidents. The disparity between the Coolidge price and Coolidge value is huge. So revision is warranted.

Coolidge was a federalist. You go back and read him and it's almost intimidating to write about him because he writes better himself than anyone. He's one of the best writers as presidents go.

We're in a kind of vicious cycle where the media tell the politicians, and the politicians tell the people, that perception is reality, and the perception of saving dooms a politician. I don't believe perception is reality, or that all Americans think that.

Coolidge was a pragmatist. He didn't start out with a tax theory. But he observed over time that lower tax rates sometimes brought in extra revenue. The success of his and Treasury Secretary Andrew Mellon's experiment with rate cuts has been obscured by our modern history books.
