In a free market there’s always scarcity and thus, work to be done, which means unemployment is a matter of choice. Governments have all sorts of ways of imposing non-voluntary unemployment. From Walter Block at mises.org:
The Creation of Jobs
If the media tell us that “the opening of XYZ mill has created 1,000 new jobs,” we give a cheer. When the ABC company closes and 500 jobs are lost, we’re sad. The politician who can provide a subsidy to save ABC is almost assured of wide spread public support for his work in preserving jobs.
But jobs in and of themselves do not guarantee well-being. Suppose that the employment is to dig huge holes and fill them up again? What if the workers manufacture goods and services that no one wants to purchase? In the Soviet Union, which boasts of giving every worker a job, many jobs are just this unproductive. Production is everything, and jobs are nothing but a means toward that end.
Imagine the Swiss Family Robinson marooned on a deserted South Sea island. Do they need jobs? No, they need food, clothing, shelter, and protection from wild animals. Every job created is a deduction from the limited, precious labor available. Work must be rationed, not created, so that the market can create the most product possible out of the limited supply of labor, capital goods, and natural resources.
The same is true for our society. The supply of labor is limited. We must not allow government to create jobs or we lose the goods and services which otherwise would have come into being. We must reserve precious labor for the important tasks still left undone.
