The article about having prisoners pick apples (TNT, 11-4) shows the downside of tightening rules on illegal immigrants. However we do have a potential workforce available to fill the gap.
All welfare recipients should be required to do some form of work for the money they receive, and this could be one way for them to contribute to society instead of just taking taxpayer money. They could be paid the same as the prisoners with half going to the state and half they keep.
Those on welfare would be money ahead since they would get their checks plus the extra that they earn. The state would also benefit from the $4-plus an hour it would receive from the wages earned by the workers. Other welfare recipients could perform work as their mental/physical abilities allow.
Refusal to work should result in removal from welfare, unless one is totally physically disabled.
