Coolidge cut the budget, and even better, cut it during peace and prosperity. He left a federal budget lower than the one that greeted him when he arrived in office. He managed to freeze or cut the budget over more than five years in office. If you look at charts of presidents - Nixon, Ike, and Reagan - you see them failing on this score.

Coolidge thought budgets were virtuous. He had his econ straight. He didn't just cut taxes, he also cut the budget.

To investors, job creation is a second-order effect. Market participants care first about interest rates, exchange rates, bond prices and the one great factor that affects all three: the long-term solvency of a bond company called the U.S. government.
