Does the minimum wage need to keep up with the cost of living?

Does the minimum wage need to track the cost of living? I'll pull recent data on purchasing power, inflation, and the policy debate.

Yes - if the goal is for the minimum wage to maintain its value, it has to keep up with the cost of living. If it does not, its purchasing power falls. Whether and how it should do so is a policy debate.

1. What happens if it doesn't keep up

The minimum wage is not automatically indexed to inflation at the federal level. When prices rise but the wage stays fixed, its real value declines:

> If the minimum wage does not keep pace with inflation, workers may struggle to afford their basic needs

> it may not provide workers with enough income to cover their basic needs and maintain a decent standard of living

To maintain employee purchasing power implies a minimum wage that corresponds to the cost of living. When the government connects the minimum wage increases to the CPI, it aims to make sure the wage keeps up with inflation. This protects the buying power of those earning the minimum wage.

Historically, this erosion has been large:

One economist noted recently: Inflation has increased so much and so fast that these measures are mostly smaller than inflation and unable to keep up

2. Arguments that it should keep up

a. Original intent was a living wage

The minimum wage was originally intended to be a living wage. When President Franklin D. Roosevelt championed the Fair Labor Standards Act of 1938, he explicitly stated that the goal was to provide a 'living wage' that supported the 'health, efficiency, and general well-being' of workers.

He famously declared that "no business which depends for existence on paying less than living wages to its workers has any right to continue in this country."

FDR defined a living wage not as a "bare subsistence level," but as "the wages of a decent living."

To many supporters, indexing simply restores that purpose.

b. Prevent erosion and provide predictability

Supporters argue indexing helps low-wage workers keep up with the rising cost of living and protects the wage from political delays.

Increasing the minimum wage annually based on CPI helps ensure that the value of the wage does not erode as much over time. CPI indexing: Such increases, in recent years no more than 2-3%, are common and a best practice in local minimum wage policies.

This is already common practice:

Other arguments for indexing are that it provides stability by automatically adjusting without the need for political fights, ensures that low-wage workers are not left behind as the cost of living increases, and that wage standards that are fixed in nominal terms and have no automatic adjustment get eroded by inflation.

3. Arguments and nuances against simple CPI indexing

Opponents and some researchers raise several points:

Business costs: Business groups argue an increase will place a huge burden on private employers. For example, opposition to New York's proposal to automatically increase the minimum wage annually by indexing it to match the rate of inflation cited a 67% increase already representing the highest increase in the state's history.

Indexing from a low base locks in low pay: Critics note that indexing the minimum wage from a low level will keep it at a low level, valuing work too little and leaving low-wage workers unable to support themselves. Similarly: indexation does little to increase the purchasing power of low-wage earners, nor does it make up for the years of declining real wages.

Regional differences: The national rate of inflation doesn't always capture cost-of-living changes in specific places. Housing, childcare, and healthcare costs can rise faster than CPI, so CPI-indexing may still leave workers behind. Alternative proposals link the wage to median wages or productivity, since improvements in productivity and economic growth have outpaced increases in the minimum wage.

Inflation feedback concerns: Some economists worry that automatic wage-price increases could contribute to inflationary pressure on small businesses, though recent empirical studies, like the 1994 New Jersey-Pennsylvania fast-food study, found jobs were sustained and employment actually increased in areas with a higher minimum wage, challenging the consensus that higher minimum wages necessarily destroy jobs.

4. Bottom line

In short: To avoid a pay cut in real terms, yes, it must keep up. Whether to index it automatically to CPI, to a local cost-of-living index, or to productivity and median wages - and at what level to start - remains the core political and economic debate.
