Perhaps Rod Livdahl (letter of 3/20) should review his Econ 101 textbook before he presents his next lesson on the subject. “Trickle Down” and “Trickle Up” are not economic terms. They are political terms, coined by Liberals to mock and distort serious economic discussion. There is no authentic “Trickle Down” school of thought that proposed the enrichment of the wealthy by government action in order to allow some of that wealth to somehow dribble down to the masses. “Trickle Up” appears to be an advanced term invented by Mr. Livdahl.
The proven policy of high-end tax reduction is informally referred to as “A rising tide lifts all boats.” As Kennedy and Reagan both conclusively demonstrated, reducing tax burdens on achievers allows them to invest their capital and genius into expanded production. This sets off a domino effect which rapidly creates jobs in existing industries and allows the dynamic development of support activities. This is the pattern that raised America from a third world country in the 1700s to the richest nation on earth in less than a century.
Conversely, the philosophy of governmental tampering with the economy, coupled with confiscatory taxation, has never produced anything beneficial. Witness the most recent examples of Cuba and the USSR.
