Even if you are not receiving food stamps, the government spends a shitload of money subsidizing farms to keep the cost of food low.
This is not necessarily true. Review what the Farm Bill all funds. Additionally, farm subsidies don't really lower the costs of food any significant amount, even if you are at the poverty level.
The government spends billions subsidizing corn production, which leads to greatly increased production, giving us the cheapest food in the world, by far.
