In the past, the United States was known as a nation of savers. Throughout much of our history American citizens typically saved 10 percent or more of their incomes annually. This discipline not only helped build a huge supply of savings to finance our growing industrial activity, but it also helped families and communities endure unexpected hardships.
However, in recent years, economists have severely downgraded savings on the economic value chain. In fact, as far as many economists are concerned, savings are a drag. Keynesians view savings as detrimental to growth because the act removes money from circulation and decreases spending (which they assume is the crucial element in creating economic growth). Policy makers, influenced by these ideas, have made rules that reward spenders and penalize savers.
As a result, Americans have, for years, spent more than we have earned. In a contained economy, like an island, this would be impossible. But in our modern world, the flow of money across borders and the seemingly magical qualities of the printing press have temporarily blinded many Americans to the simple truth that we can't consume more than we produce, or borrow more than we save...at least not for very long.
