We often think of a job as a source of income for workers. But jobs represent much more for society and individuals. Countries grow, for instance, when more people work, when each job in the economy becomes more productive, and when people move from low to higher productivity jobs. A good portion of the reduction in poverty that we have seen worldwide can be explained by an increase in the labour income of the poor, their main source of income. Jobs also contribute to the accumulation of human capital and promote social stability. A young person who is employed learns on the job, gains experience, makes other workers in the economy more productive and is less likely to engage in risky or criminal behaviour.
