Meanwhile, crops spoil in the field?
Great ideas long-term. But the article is a bit self-righteous as to the here-and-now.
Meanwhile, perhaps we pay slightly more for vegetables during the transition, and the farmers pay enough to get more of our unskilled unemployed out there in the field. Perhaps we recognize that in the time it takes to get the enforcement side working as if we were serious, we can get the legal immigration process working. I don't think it's impractical for the here-and-now, if "here-and-now" means the next year rather than the next two hours.
