Fratelli Tutti §20
Fratelli Tutti: On Fraternity and Social Friendship
20 This way of discarding others can take a variety of forms, such as an obsession with reducing labour costs with no concern for its grave consequences, since the unemployment that it directly generates leads to the expansion of poverty. In addition, a readiness to discard others finds expression in vicious attitudes that we thought long past, such as racism, which retreats underground only to keep reemerging. Instances of racism continue to shame us, for they show that our supposed social progress is not as real or definitive as we think.
