The pope castigated unemployment, underemployment, inadequate wages, automation and a lack of job security as violations of human dignity. These conditions, he wrote, were forces that negated self-esteem, personal satisfaction, responsibility and creativity. The exaltation of the machine, he warned, reduced human beings to the status of slaves. He called for full employment, a minimum wage large enough to support a family, the right of a parent to stay home with children, and jobs and a living wage for the disabled. He advocated, in order to sustain strong families, universal health insurance, pensions, accident insurance and work schedules that permitted free time and vacations. He wrote that all workers should have the right to form unions with the ability to strike.
