Economist Frederick Thayer has studied the history of our balanced-budget crusades and has come up with some depressing statistics. We have had six major depressions in our history (1819, 1837, 1857, 1873, 1893 and 1929); all six of them followed sustained periods of reducing the national debt. We have had almost chronic deficits since the 1930s, and there has been no depression since then - the longest crash-free period in our history.
