Today, the agricultural sector has essentially taken on the characteristics of business and industry generally. In contemporary usage, a "farmer" is someone who owns and operates a farm, which more often than not will be a sizable business enterprise; "agricultural workers" or "farm workers", who perform the actual work associated with farming, typically come out of the lower classes; indeed, they are often near-destitute immigrants or migrant farm workers. In this respect, farming mirrors big business: like any enterprise, a farm has owners (who may be a family or a corporation), salaried managers, supervisors, foremen and workers.
