Actually, the labor market was allowed to retain its main function only on condition that wages and conditions of work, standards and regulations should be such as would safeguard the human character of the alleged commodity, labor. To argue that social legislation, factory laws, unemployment insurance, and, above all, trade unions have not interfered with the mobility of labor and the flexibility of wages, as is sometimes done, is to imply that those institutions have entirely failed in their purpose, which was exactly that of interfering with the laws of supply and demand in respect to human labor, and removing it from the orbit of the market.
