Oh this sounds so familiar ... USA or Canada ... price goes up, though usually it's not the producer that is getting the extra $$$$, rather all those who are involved in the chain from moo to you. Similarly other commodities!
Great figures OKSewGlad ... the primary producers continue to do a better job of producing food for all.
1910 ... one farmer produced enough food to feed 12 people
Today ... one farmer produces enough for 130 people!
(note, one farmer, not one farm ... so the numbers would go up incrementally dependant on the work force involved)
