But agricultural studies are working as intended? The U.S. government has decided that it's in our national security interest to remain a net exporter of crops. If World War III broke out and all the borders shut down, America would still be able to feed herself. The U.K. wouldn't. There would be mass starvation in much of the first world, and people would say "the government should've done something." All the diabetes is a pretty rough unintended consequence, I'll give you that, but shifting some chip fabs to our shores as a matter of national security doesn't sound like too bad of an idea.
