Rural America is the source of our food production and small towns support the farmers who produce our food. If there is a migration from these rural areas it cannot help but lower food production. Perhaps the Marxists who run the Biden Administration will force food production into government run collective farms. Those worked so well in Russia and other Communist countries.
This is actually surprising given how much political pull ADM and Monsanto have. Cooperate farms take 2% of the farms and only 12% of the production the vast majority is medium and large family or privately owned farms. With annual revenues of $350,000 plus.
