There was once a time when we talked about ‘just’ prices and “the common good.” The idea behind “just price”, or the related idea of the “just wage”, came out of a healthy pre-modern sense of social stability and inclusion: the price you pay to a grower, a sewer or an artisan for his or her products must recognize the real cost of living for that worker and his or her family; it can’t reflect only the usefulness of the product to the purchaser. “Price” had to include solidarity: the acceptance of ongoing responsibility for all the members of the community.
