44 There is also the threat of unemployment, a source of anxiety and unhappiness for many men. And this problem can entail even greater difficulties today, when men are being replaced by all sorts of advanced machines. Of this kind of unemployment, Our predecessor of happy memory, Pius XI, uttered this complaint: "There are," he said, "honest working men almost beyond number who want only an opportunity to earn by honest means that daily bread for which, by divine command, we entreat our Father in heaven. But, instead, they are reduced to idleness and, along with their families, reach the very depths of privation. Their unhappiness touches Our heart; We are constrained to take pity and to repeat the merciful words that came from the heart of our Divine Master when He saw the multitude languishing in hunger: 'I have compassion on the crowd' (Mark 8.2)."(15)
