There's a floor on what they can charge, though: the cost of maintaining the land, the cost of labor to harvest, the cost to process the peaches and package them, the cost to ship them to the store, and the store's cost to hold them in inventory before you buy them.

A business cannot stay in operation if the only way to sell the product is to sell it below cost[0]. Having all this excess production is exactly why Del Monte failed as a company. There's no point in building a business to provide people with below-cost food; it's not sustainable and is ultimately wasteful.

Find a way to get the peaches from the trees to people's homes cheaper? Great, do that, and maybe you can sell more at a lower price.

Or produce fewer until you can sell at a price above cost without much waste. We don't wring our hands at factory owners when they don't manufacture a huge surplus of toys that no one wants to buy. We shouldn't be upset when farmers decide to stop growing as much of a certain crop because they can't sell it all. I get the visceral reaction against killing trees. But that's an emotional response that has nothing to do with the reality of the situation. I would much rather that land be used for a more productive crop that people actually want to buy, at prices that reflect what it costs to produce.
