THE FALLACY OF REFUSING TO RAISE TAXES FOR THE RICH

In February of 2005 I wrote a blog in support of the progressive income tax. Given the current Republican refusal to consider any tax increase for the rich and the proposals to substitute a Value Added Tax for a large portion of the Income Tax, I believe that my blog comments retain their relevancy. As a result I am reprinting the original blog below with some added comments at the end:

PROGRESSIVE INCOME TAXES EQUALIZE THE PAIN
Tax policy usually relies on either of two principles: The “Ability to Pay Principle” or the “Benefit Principle”. Both of these forget the fact that paying taxes is painful. If possible we would all like to pay as little as possible to the various levels of government. However, as long as we have to support our government we should make sure that when we pay taxes we are “equalizing the pain” to each of us. The problem with “Flat Taxes”, “Value Added Taxes”, and the various consumption taxes is that they tend to distribute the pain to the lowest economic levels in society. To see how this applies we need to look at the satisfaction people get from having income and/or wealth.

It is well known that as people obtain more and more of a good or service the satisfaction they get from the last unit of the good is lower than the satisfaction received from the immediately prior unit. In economics this is known as the Law of Diminishing Marginal Utility. This “law” applies to income and wealth as well as the consumption of goods and services. The more income or wealth you have, the less each additional dollar of income or wealth means to you in terms of your over all satisfaction.

Applying this to tax policy we can see that a 20% flat tax would cost $4,000 to a person with a taxable income of $20,000 per year and $20,000 to a person with a taxable income of $100,000 per year. In terms of the ability to enjoy the fruits of the economic system, the $4,000 to the low income individual is a much greater sacrifice than the $20,000 is to the high income individual. Equalizing the pain of paying taxes would require that the low income person pays a lower tax rate or the higher income person faces a higher tax rate or some combination of lower and higher rates.

Progressive income taxation is not a “soak the rich” scheme. It is the only system which has the capability of equalizing the pain of supporting government.

The problem with a VAT (Value Added Tax) is that it has lower income households paying a large portion of their income in taxes than higher income households. This is because all spending is taxes under a VAT. Assume that the VAT is 14% (this is low compared to most VAT countries). A family of 4 with an income of $40,000 per year will probably have no Saving. This means that the whole $40,000 would be subject to VAT and the Tax paid of $5,600 would be 14% of their income. A household with an income of $400,000 per year would have a saving rate approximately 20%. They would be spending $320,000 with a VAT of $44,800. This is 11.2% of the higher income family's gross income. In other words the low income family has a higher effective rate of taxation than the high income family.

ADDITIONAL COMMENTS REGARDING THE VAT

Please remember that the VAT results in a lower quality of life at the lower income level because the low income VAT payment means that true spending on goods and services is $34,400 which is the $40,000 less the $5,600 VAT. The higher income families can opt lower net spending of reduce their saving to maintain the quality of life. Even if this decision is made, the high income effective tax rate would still be lower than the effective rate paid by the lower income family. The numbers are slightly off for the low income family because the VAT would be applied to only their spending.The math works out to Spending of $35.087.72 and VAT Taxes of $4,912.28 or 12.2% of gross income.The high income family still has a lower effective tax rate of 11.2% if they pay the tax by reducing their saving. If they reduce their spending the would spend $280,701.75, have a VAT of $39,298.25, and have a effective tax rate of 9.82%.

All in all the lower income people pay a higher percentage of their income than the higher income people. This is the definition of a regressive tax system.
