Many Americans, perhaps a substantial majority, still believe that, irrespective of any problems they may have caused, labor unions are fundamentally an institution that exists in the vital self-interest of wage earners. Indeed, many believe that it is labor unions that stand between the average wage earner and a life of subsistence wages, exhausting hours of work, and horrific working conditions.

Labor unions and the general public almost totally ignore the essential role played by falling prices in achieving rising real wages. They see only the rise in money wages as worthy of consideration. Indeed, in our environment of chronic inflation, prices that actually do fall are relatively rare.

Nevertheless, the only thing that can explain a rise in real wages throughout the economic system is a fall in prices relative to wages. And the only thing that achieves this is an increase in production per worker. More production per worker — a higher productivity of labor — serves to increase the supply of goods and services produced relative to the supply of labor that produces them. In this way, it reduces prices relative to wages and thereby raises real wages and the general standard of living.

What raises money wages throughout the economic system is not what is responsible for the rise in real wages. Increases in money wages are essentially the result just of the increase in the quantity of money and resulting increase in the overall volume of spending in the economic system. In the absence of a rising productivity of labor, the increase in money and spending would operate to raise prices by as much or more than it raised wages. This outcome is prevented only by the fact that at the same time that the quantity of money and volume of spending are increasing, the output per worker is also increasing, with the result that prices rise by less than wages. A fall in prices is still present in the form of prices being lower than they would have been had only an increase in the quantity of money and volume of spending been operative.

With relatively minor exceptions, real wages throughout the economic system simply do not rise from the side of higher money wages. Essentially, they rise only from the side of a greater supply of goods and services relative to the supply of labor and thus from prices being lower relative to wages. The truth is that the means by which the standard of living of the individual wage earner and the individual businessman and capitalist is increased, and the means by which that of the average wage earner in the economic system is increased, are very different. For the individual, it is the earning of more money. For the average wage earner in the economic system, it is the payment of lower prices.

What this discussion shows is that the increase in money wages that labor unions seek is not at all the source of rising real wages and that the source of rising real wages is in fact a rising productivity of labor, which always operates from the side of falling prices, not rising money wages.

Indeed, the efforts of labor unions to raise money wages are profoundly opposed to the goal of raising real wages and the standard of living. When the unions seek to raise the standard of living of their members by means of raising their money wages, their policy inevitably comes down to an attempt to make the labor of their members artificially scarce. That is their only means of raising the wages of their members. The unions do not have much actual power over the demand for labor. But they often achieve considerable power over the supply of labor. And their actual technique for raising wages is to make the supply of labor, at least in the particular industry or occupation that a given union is concerned with, as scarce as possible.

Thus, whenever they can, unions attempt to gain control over entry into the labor market. They seek to impose apprenticeship programs, or to have licensing requirements imposed by the government. Such measures are for the purpose of holding down the supply of labor in the field and thereby enabling those fortunate enough to be admitted to it, to earn higher incomes. Even when the unions do not succeed in directly reducing the supply of labor, the imposition of their above-market wage demands still has the effect of reducing the number of jobs offered in the field and thus the supply of labor in the field that is able to find work.

The artificial wage increases imposed by the labor unions result in unemployment when above-market wages are imposed throughout the economic system. This situation exists when it is possible for unions to be formed easily. If, as in the present-day United States, all that is required is for a majority of workers in an establishment to decide that they wish to be represented by a union, then the wages imposed by the unions will be effective even in the nonunion fields.

Employers in the nonunion fields will feel compelled to offer their workers wages comparable to what the union workers are receiving — indeed, possibly even still higher wages — in order to ensure that they do not unionize.

Widespread wage increases closing large numbers of workers out of numerous occupations put extreme pressure on the wage rates of whatever areas of the economic system may still remain open. These limited areas could absorb the overflow of workers from other lines at low enough wage rates. But minimum-wage laws prevent wage rates in these remaining lines from going low enough to absorb these workers.

From the perspective of most of those lucky enough to keep their jobs, the most serious consequence of the unions is the holding down or outright reduction of the productivity of labor. With few exceptions, the labor unions openly combat the rise in the productivity of labor. They do so virtually as a matter of principle. They oppose the introduction of labor-saving machinery on the grounds that it causes unemployment. They oppose competition among workers. As Henry Hazlitt pointed out, they force employers to tolerate featherbedding practices, such as the classic requirement that firemen, whose function was to shovel coal on steam locomotives, be retained on diesel locomotives. They impose make-work schemes, such as requiring that pipe delivered to construction sites with screw thread already on it, have its ends cut off and new screw thread cut on the site. They impose narrow work classifications, and require that specialists be employed at a day’s pay to perform work that others could easily do — for example, requiring the employment of a plasterer to repair the incidental damage done to a wall by an electrician, which the electrician himself could easily repair.

To anyone who understands the role of the productivity of labor in raising real wages, it should be obvious that the unions’ policy of combating the rise in the productivity of labor renders them in fact a leading enemy of the rise in real wages. However radical this conclusion may seem, however much at odds it is with the prevailing view of the unions as the leading source of the rise in real wages over the last hundred and fifty years or more, the fact is that in combating the rise in the productivity of labor, the unions actively combat the rise in real wages!

Far from being responsible for improvements in the standard of living of the average worker, labor unions operate in more or less total ignorance of what actually raises the average worker’s standard of living. In consequence of their ignorance, they are responsible for artificial inequalities in wage rates, for unemployment, and for holding down real wages and the average worker’s standard of living. All of these destructive, antisocial consequences derive from the fact that while individuals increase the money they earn through increasing production and the overall supply of goods and services, thereby reducing prices and raising real wages throughout the economic system, labor unions increase the money paid to their members by exactly the opposite means. They reduce the supply and productivity of labor and so reduce the supply and raise the prices of the goods and services their members help to produce, thereby reducing real wages throughout the economic system.
