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.

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.

With demands for special education or standardized test prep being shouted in their ears, public schools can't always hear a parent when he says: 'I want my child to be able to write contracts in Spanish,' or, 'I want my child to shake hands firmly,' or, 'I want my child to study statistics and accounting, not calculus.

Coolidge and his treasury secretary Mellon loved new technology. Like JFK, C.C. divined that a new technology could lift the nation out of its doldrums; the only difference was that JFK's new technology was space travel, and Coolidge's travel by airplane.

Fame is worth less than service.

Economics are part of our life. We try to treat them separately, like over there is the economy and here is history. Econ affects history and history often doesn't get it right if it doesn't respect econ.

Coolidge believed that government officials who tell themselves that spending benefits the economy delude themselves and the citizens. Government budgets promote human freedom.
