Seasonal farm workers move from field to field across the US at harvest time, they don't come from where the harvest is. There are hundreds of miles between jobs, farmworkers can't commute from home to the worksite.

Suggestions welfare recipients could do the job if denied benefits are senseless, the costs would be outrageous, most welfare recipients are female and have minor dependants, you'd need to provide housing, daycare, schooling and medical services, and plenty of welfare recipients would still be unemployable due to other handicaps. If you set off from the proposition to revoke any of their rights to public assistance there'd be savings since no housing, daycare, school or medical service would be required, but I suspect you'd have a revolution before they gave up these benefits.
