There was once a time when almost everyone had to be involved in food production for everyone to eat. Now it is less than 1% of the people. Today almost everyone creates wealth...
More wealth will bring higher demand for high quality, sustainably grown/raised food(and low skill jobs). My Japanese wife refuses to eat American eggs because they taste so terrible.
Mostly a machines job. Agriculture will not go back to employing a lot of people as if would make food too expensive to buy.
