But what about the thousands of high-priced community-supported agriculture programs and farmers’ markets that have sprouted up around the country? Nope. These new venues were promising when they proliferated over a decade ago, but now, with so many programs to choose from, there is increasing pressure for farmers to reduce prices in cities like my hometown, New Haven. And while weekend farmers’ markets remain precious community spaces, sales volumes are often too low to translate into living wages for your much-loved small-scale farmer.

Especially in urban areas, supporting your local farmer may actually mean buying produce from former hedge fund managers or tax lawyers who have quit the rat race to get some dirt under their fingernails. We call it hobby farming, where recreational “farms” are allowed to sell their products at the same farmers’ markets as commercial farms. It’s all about property taxes, not food production. As Forbes magazine suggested to its readers in its 2012 Investment Guide, now is the time to “farm like a billionaire,” because even a small amount of retail sales — as low as $500 a year in New Jersey — allows landowners to harvest more tax breaks than tomatoes.

On top of that, we’re now competing with nonprofit farms. Released from the yoke of profit, farms like Growing Power in Milwaukee and Stone Barns in Pocantico Hills, N.Y., are doing some of the most innovative work in the farming sector, but neither is subject to the iron heel of the free market. Growing Power alone received over $6.8 million in grants over the last five years, and its produce is now available in Walgreens stores. Stone Barns was started with a $30 million grant from David Rockefeller. How’s a young farmer to compete with that?

As one grower told me, “When these nonprofit farms want a new tractor, they ask the board of directors, but we have to go begging to the bank.”

And then there are the chefs. Restaurants bait their menus with homages to local food, attracting flocks of customers willing to pay 30 bucks a plate. But running a restaurant is a low-margin, cutthroat business, and chefs have to pay the bills, too. To do so, chefs often use a rule of thumb: Keep food costs to 30 percent of the price of the meal. But organic farming is an even higher-risk, higher-cost venture, so capping the farmer’s take to a small sliver of the plate ensures that working the land remains a beggar’s game.
