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

Coolidge's stat was so low; he's ranked in the bottom half of presidents. What I found when I encountered this man was the leader I might like to see today.

In the end, all new schools, public or private, snobby or not, add value to the education market, making it bigger and more efficient, in the same way that Zuckerberg added wealth to the economy even for non-Facebook fans.

The difference between recession and depression is simple. Recession, goes the saying, is when you lose your job; depression is when I lose mine.

In a way, Calvin Coolidge is better than Reagan. His tax rates were lower, and he cut budgets.

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.

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.
