Whereas I'm inclined to agree with you — on the surface — I fear that may be a short-term fix. I expect people will turn their ingenuity towards high yield organic farming like they do in the Netherlands, unless we can persuade the world that actual "sun grown in soil" is better than automated hydroponics.

Personally? We're increasingly turning to growing our own. Which I think is cool, and I think more and more people are doing that... but it somewhat skirts the re-employment issue.
