Basic problem solving
Here is the problem statement: Farms are having difficulties when they hire illegal immigrants in that if there is a chance of an INS raid, the workers do not come to work for fear of being deported. This causes a drop in productivity and ultimately profitability for the farm.
* My Solution: Quit hiring illegal immigrants. Do more thorough checks on the documentation provided by your employees and make sure that they are legally allowed to work in the United States before you hire them.
* Alternate Solution: Do not allow immigration raids. Create a 'safe harbor' area where illegal immigrants can come and work without the fear of being rounded up and deported.
Perhaps it's just me, but I think that it is going to be very difficult to find a solution to our immigration challenges in the United States when he have whole municipalities that are prepared to go on record as defying Federal law.
