The True Story on How Economics Works June 17, 2004

Robert Bartley, former editor of the Wall Street Journal (may he rest in peace), has written one of the best accounts of the 1980s economic policies, explaining what led to the economic growth, and what can be done to re-create these policies once again.
Many people who claim to oppose supply-side economics never explain how the theory works. The notion that Reagan's tax cuts were mere "trickle down" economics is buttressed by the fact that no one claims that the money will "trickle down." That is not how the economic philosophy works in theory or in practice. Instead, the theory considers high taxes to be another example in which a high cost placed on a product or service is likely to result in fewer interested buyers. Similarly, high marginal tax rates are more likely to stiffle growth since the reward for working additional hours is diminished. Those with small businesses, or those who invest, may decide that the extra work will not translate into higher returns, and thus may produce less. That is not good for the economy because this stiffles economic growth, and is a recipe for stagnation, which is exactly what happened in the 1970s. So reduce taxes to create more growth. The marginal rate fell from 70% to 28% during Reagan's tenure.

The other part of Reagan's program was to have a tigheter monetary policy. By tightening the dollar, it would reduce inflation. Thus, tighten the dollar, reduce inflation, and reduce taxes, and create growth. That is exactly what happened. During Reagan's tenure, inflation went down and growth went up. THIS IS AN INDISPUTABLE FACT.

The left does not like this theory because it contradicts the notion that government has an effect in creating economic growth.
