James Piereson talked about three political revolutions that set the stage for new phases of political and economic development in America: Thomas Jefferson’s “revolution of 1800,” the Civil War, and the New Deal. He also described his belief that the U.S. was on the verge of a fourth revolution, due to high debt levels, a stagnant economy, impending retirements of the Baby Boomer generation, and polarized politics. He used some graphs during his presentation and afterwards responded to questions from members of the audience. 
“The Fourth Great Political Revolution: 1789, 1858, 1928, and Today” was the monthly American Enterprise Institute Bradley Lecture.
