Mater et Magistra §94

⁹⁴ For although many unjust and inhuman economic and social imbalances still exist in our day, and there are still many errors affecting the activity, aims, structure and operation of economies the world over, it is an undeniable fact that, thanks to the driving impulse of scientific and technical advance, productive systems are today rapidly becoming more modernized and efficient—more so than ever before. Hence a greater technical skill is required of the workers, and more exacting professional qualifications. Which means that they must be given more assistance, and more free time in which to complete their vocational training as well as to carry out more fittingly their cultural, moral and religious education.
