The government already subsidizes private overproduction on US farmland. USAID was, at its heart, a farm subsidy.

And it should be said that most 'small' farmers in the US are millionaire scions and shouldn't need subsidies to make a profit in most parts of the US (we have abundant natural resources).

More than half of all calories produced in the US are not even for human consumption. And globally enough calories to feed every human on earth are lost to inefficiency each year.

We can all benefit from a better system of distribution and production without getting lost in the magical thinking of a public/private false dichotomy.
