1. Everything is linear.
The idea that cutting the top tax rate from today’s level, 35% ordinary income will produce the same result as a cut like Reagan’s 70% to 28%. Many factors play into how well money moves through the economy. The only transactions that produce value directly are purchases for goods and services. Everything else creates money for future purchases of goods and services. “Future” is the key there.
2. Constant Credit
Credit is treated as a constant, but in reality it involves a cycle and is very key to money velocity and how effective investment results in down stream benefits. This is key as to why supply side economics does not consistently work. Demand can not be ignored and the boom bust cycle of credit should not be ignored.
3. Credit… I mean SAVINGS is key
The white elephant in the room. Everyone talks a good talk about savings and how important it is to have a healthy environment. The reality with today’s system is that deficit spending at a government level and private level is required to maintain the growth. The record string of 3% or higher growth that Bush II achieved was done via home investment. Credit went haywire in that companies took on unprecedented risk for immediate profit. We are still paying years later as the credit cycle still unwinds. Reagan ran 4% plus deficits. How do we grow without blowing up the next credit cycle? without blowing up the credit worthiness of the USA?
4. Investment gains are greater the working man.
A dollar that enters the system via an investment gain versus a dollar that enters the system via a pay check provides more lift to the economy. Fortunately even Ronald Reagan understood this fallacy and set the capital gains rate at the same level of ordinary income. The end consumer and health care spending accounts for 70% of GDP. Money spent on goods and services is a direct shot to the economy. Investment, while very much needed, trickles down indirectly which requires strong money velocity to produce the intended effect.
The right would like you to believe that tax cuts are the cure all, all the way down to a zero tax rate. The reality is that capital economic systems are complex. There are many variables, many of which are critical but often ignored. Unfortunately, understanding the complexities and where the “sweet spot” exists for taxation gets buried under rhetoric on both sides.
The entire system must be looked at as a whole. Cutting the top bracket from 35% to 25% may not produce the gains expected when capital gains rate is already at 15%. Higher unemployment for 20 years may be better than running extreme deficits. Lowering business tax rates may be more productive than further adjusting individual tax rates.
Unfortunately opinion rules Washington rather than fact. As a result we have gotten very different tax rates, which always creates uncertainty. Let’s just chock that up to another left and right fallacy, which is “we are always right”.
