The Percentage Fallacy: A Modest Proposal

Have you noticed how many financial choices are calibrated, not in dollars and cents, but in percentages?  Raises. Cost of living adjustments. Tips for servers. Taxes. One of the insidious effects of such percentage adjustments is to widen the gap between the haves and the have-nots, hie rich and the poor.

A few examples.  You and a friend go out to lunch, paying separately. You are hungry, she is not. The effort by the server is not proportional to the dollar value of your order.  Your bill for food including tax is $45, hers is $20. You both give a 20% tip. You add $9, she adds $4. Does that make any sense? If you are paying the waiter for his service, shouldn’t the tip each of you pay represent the quality of service and not the price of the meal? I’m not trying to stiff servers here, just being a little more egalitarian.  I don’t tip at drive-in windows or fast food restaurants where the service is minimal, but I will probably tip more at a fancy restaurant than a pizza joint. Perhaps it should be a function of how long we spend sitting there, preventing someone else from claiming that space and generate another tip. Or, if there is a single payer, perhaps the tip should reflect the number of people served rather than the total cost.

Second example. Social Security, or anything that else is adjusted for the increase in the cost of a representative basket of goods and services purchased by the average household.  Let’s take this coming year, where the COLA for Social Security will be 2.7%. The average monthly Social Security benefit in July 2025 was just over $2000. A 2.7% raise is another $54 a month for a single individual.  The maximum benefit is $6000, resulting in a raise of $162 a month.  Don’t these two retirees pay the same price for a gallon of gas or a loaf of bread?  And what if you are down at the lower end of the scale, say a monthly benefit of $1000 a month?. Your raise is a stingy $27 a month. In fact, it probably won’t even cover the increase in your Medicare premium except maybe for those at the top of the scale..

A similar inequity exists when an employer, often a state government, proclaims percentage raises across the board.  The $15,000 a year custodian gets a 5% raise to $15,750 and the $90,000 engineer sees his salary rise to $94,500. Basic costs go up for both, but the difference in COLA widens the income gap.

There is a place for percentages.  I give 10% of my income to charity, a guideline set by Hebrew scriptures that has had remarkable staying power. The tithe embodies the idea is that one has been blessed, the more one is expected to contribute. And I certainly understand the rationale for other kinds of raises, for meritorious performance or to retain a valued employee in a competitive market.  But if it is a COLA, both the poor and the rich see the increase in price of bread, the rent or mortgage for housing, the gallon of gas, the kilowatt of electricity. Wealthier households have more flexibility in adjusting to inflation.

So, what’s the answer?  For tips, it’s a matter of personal preference. If I am taking my daughter and granddaughter to lunch, I tip on the basis of the number served. If it’s just me, I usually tip $4-5 unless the service is exceptional. For a COLA, a solution is even simpler. The average Social Security recipient’s monthly check is $2,000. The COLA is 2.7% of $54 a month. Why shouldn’t everyone get the same dollar amount? should one person get $27 and another $162 and someone else get $27 a month when the basket of goods being priced is the same? In a nation of rapidly rising inequality, why do we let COLAs exacerbate the gap?

Saving Social Security

There are a lot of small steps that could be taken to save Social Security.  Raising the retirement age is not such a hot idea. It penalizes workers who work in more strenuous and low wage jobs, often accompanied by lower life expectancy. It assumes that all potential retirees ae equally able to continue working even if they are in declining health (but not bad enough to qualify for disability). 

Let’s explore a couple of options that would shift more of the cost to those who need Social Security least. First, remove or at least greatly increase the cap on how much of your wages and salary are subject to social security taxes.  Second, put a cap on the amount of your income that is counted toward determining your benefits.  And finally, rethink the COLA.

The first two are not complicated.  There has always been a cap on the amount of earnings that are taxed, although there is no good reason for it. Higher income workers often have additional non-wage, non-salary income that is only subject to ordinary income tax, not Social Security taxes.  Average workers seldom do. Those who don’t work at all but live off their income from capital don’t contribute anything. Whatever happened to the social part of Social Security, which suggests we are all in this together?

For 2024, that cap on social security taxes is set at a wage and salary income of $168,600, adjusted each year based on the percentage increase in average wages. I don’t see any particular need for a cap, other than lobbyists for wealthier citizens appearing to have the ear of Congress. But if there is a cap, it should be set at something like 80th percentile of wage and salary income. (That’s the amount that has 80% making less and 20% making more.)  That way, when people get outrageous salaries for heading a nonprofit, a corporation, a university, or a football program, they will be carrying a fairer share of the cost of keeping our old folks out of poverty.

We don’t want the very wealthy to get more benefits just because they increase their contributions, so the wage /salary base used to compute the monthly check should be capped at some at something like the 60th percentile of the individual’s average wage and salary income used to determine benefits.

Lastly, the COLA or cost of living adjustment , which is based on the inflation rate for the 12 months ending the previous June 30th.  COLAs are a great engine of inequality.  In South Carolina, pension reform a decade ago included a cap on increases..  We state retirees get a one percent increase every year regardless of actual inflation, but there is a cap is of $500. That’s one percent of $50,000. Any pension greater than that gets the same $500 a year raise.

Think about it.  Jane’s Social security benefit check is $2,000, just a shade above the average of $1907.  average, about $1900.  Dick’s check is the maximum of $4873, which we will round down to $4800 for easy calculation. . Both must contend with higher prices for housing, groceries, and insurance. This year’s 2.5% COLA gives Jane $50 more a month while Dick gets an extra $120.  The percentage gap between their incomes is unchanged, but percentages don’t pay the electric bill. The dollar gap has risen from $2800 to $2870, and that gap grows year after year.A cap on the COLA like South Carolina’s (about $5 a month) would be more equalizing. Or setting the cap at the COLA percentage of the average benefit and give that to everyone, which would do ven more fot those at the bottom of the scale. Let’s think creatively here!

After we survive the election, let’s go back to thinking about how a civilized society that believes in fairness would shore up Social Security with more revenue and slower growth of overall benefit, with the scales tipped toward the lower half of the income spectrum.  And January is not too soon to get started. We can call it The Other Project 2025.

Saving Social Security and Medicare

I am a more or less blue person in a very red state. So I don’t write my representatives in Congress very often. I do lobby my state legislators whom I know personally and have a pretty good rapport with. But every now and then my economist self joins the fray and, having spent my career in a very conservative department, I practice the art of framing my argument from the right of where they are. Today it was Social Security and Medicare, and I was not lying when I said I was a fiscal conservative. I am. And this is a fiscally conservative argument.

Dear…

I am writing to you because I am concerned about the future of Social Security and Medicare.  I know that both parties are committed to their survival and fiscal health. It is an intergenerational contract that has been with us for 88 years and one that our children and grandchildren are counting on as a safety net for their retirement.

As a fiscal conservative, I believe that we must pay for what we get from government.  Since these two programs are supported by FICA contributions, that source is the right place to look for funding. These Social Security and Medicare contributions are NOT taxes. They represent the cost of a retirement pension and insurance premiums for health care and for the possibility of outliving one’s assets. They are grounded in the ability to pay by making them a percent of income, and like many state defined benefit programs, they come with an employer match as deferred compensation and purchase of insurance

I would recommend a modest increase in the employer and employee premium from 7.6% to 8% and a significant increase in the wage cap to provide the additional funds.

Thank you for your consideration.

Sincerely,
