That whole farmer Joe thing is a fantasy anyway. The small time farmer isn't hiring illegals anyway, he cant afford illegals. It's the big business farms with stockholders and all that are hiring illegals.
There is a vegetable farmer right up the road from me who has a farm crew to pick his crops and do his field and orchard labor. I did not ask to see their passports, but if I had to guess, I'd say all illegals. We're not talking some giant corporation. What used to be a family farm (and still is) that has branched out into vegetables and plants with a roadside market.
