There is no such thing as cheap food.  You will pay for it one way or another, either directly or through subsidies to producers and processors.  Sometimes the subsidies are direct; USDA payments, subsidized crop insurance premiums, cost share for land and building improvements, etc., and sometimes it is less direct, like deliberately refusing to enforce immigration law so that illegal workers can flood the market and either drive down wages or preclude automation and mechanization that has a steep entry fee.  One way or another, you pay for it in the end.  The main difference is that when the government subsidizes production, it does so at least partly with borrowed money, so that the real cost will be deferred to the next generation.
