The improvement in the workers’ material conditions is due to the increase in the per capita quota of capital invested and the technological achievements which the employment of this additional capital brought about.
As far as labor legislation and union pressure did not exceed the limits of what the workers would have got without them as a necessary consequence of the acceleration of capital accumulation as compared with population, they were superfluous. As far as they exceeded these limits, they were harmful to the interests of the masses. They delayed the accumulation of capital thus slowing down the tendency toward a rise in the marginal productivity of labor and in wage rates. They conferred privileges on some groups of wage earners at the expense of other groups. They created mass unemployment and decreased the amount of products available for the workers in their capacity as consumers.
If unions were really bargaining agencies, their collective bargaining could not raise the height of wages above the point of the unhampered market. As long as there are still unemployed workers available, there is no reason for an employer to raise his offer. Real collective bargaining would not differ from individual bargaining.
What is euphemistically called collective bargaining by union leaders and “pro-labor” legislation is bargaining at the point of a gun. It is bargaining between an armed party, ready to use its weapons, and an unarmed party under duress. It is not a market transaction.
It is a dictate forced upon the employer and it produces institutional unemployment. If a government decree or labor union pressure and compulsion fix wage rates above the height of the potential market rates, institutional unemployment results. The problem is not the right to strike, but the right—by intimidation or violence—to force other people to strike, and the further right to prevent anybody from working in a shop in which a union has called a strike. When the unions invoke the right to strike in justification of such intimidation and deeds of violence, they are on no better ground than a religious group would be in invoking the right of freedom of conscience as a justification for persecuting dissenters.
