You realize that the farmers produce the peaches, right? And that if it costs more to harvest them that the peaches are worth, you don't harvest them. Then you have a giant pile of rotten peaches anyway that has to be cleaned up, so maybe you harvest them anyway and take the loss yourself. Fine.
Now you - the farmer - have a surplus of peach trees that will grow new peaches, and those new peaches won't sell either. You'll take loss year after year this way. No, the best thing to do is to repurpose the land for something else, and that means uprooting the peach trees. It's a good thing there's federal grant money to absorb some of that cost.
Capitalism is where there's an ownership class that contributes essentially nothing and a labor class that produces the value, and the former exploits the latter. This situation is not that; the farmer is (ideally) the labor (unless factory farms, or unfair compensation otherwise). The peaches having more or less worth due to market conditions is because of a free market, which is distinct from capitalism.
Growing crops is work. Harvesting crops is work. Transporting, processing, inspecting, warehousing, inventorying, packaging, retailing - all work. People - workers - expend effort to create the value of cans of peaches in pantries, and each person should be compensated fairly for the value their effort produces.
Never anywhere in my commentary did I refer to profits. If the peaches are worth less than they cost to harvest, the value of the labor already invested is lost, and the farm as a whole is at risk. Especially for the remaining family farms, this means that corporate farm companies will buy the land and consolidate their power. It's a good thing there's federal grant money to absorb some of the cost of retooling.
I'm as anti-capitalist as they come, and there's parts of this situation to be justifiably pissed about. The fact that a single cannery closing results in this is one. The fact that the corporation that ran that cannery may well have closed it for profit reasons is another. But getting pissed about repurposing land for something more useful? Seems ill informed.
