Many of the other potential goods of work are enjoyed by some workers, but many receive little social recognition or do not achieve a greater sense of community through their work. A good deal of socially valuable or ‘essential’ work is largely invisible to its beneficiaries. Many jobs are dull or unchallenging, contributing little to the development or exercise of our more sophisticated human capacities. It is difficult to envision, for instance, that toll booth workers find their jobs or stimulating or challenging (aside from testing their ability to withstand repetition or boredom).
