From Field to Shelf: The Corporate Chokehold That Keeps Farmworkers Poor While Retail Giants Pocket Billions

The Price of a Tomato

Somewhere in Immokalee, Florida, a farmworker rises before dawn to pick tomatoes that will be on a Walmart shelf within 48 hours. She earns, on average, around $13,000 per year — a figure that has barely moved in real terms over the past two decades. Meanwhile, Walmart reported $674 billion in net revenue in fiscal year 2024, and Amazon's North American retail segment generated over $386 billion. The distance between those numbers is not a market outcome. It is a power structure.

America's food supply chain has undergone a quiet but seismic consolidation over the past thirty years. What was once a diverse ecosystem of regional grocers, independent distributors, and competitive buyers has been compressed into a system dominated by a handful of mega-retailers whose purchasing power is so vast that the farmers and growers who supply them have no meaningful ability to negotiate. And when farmers cannot negotiate, the people who work their fields bear the cost.

The Mechanics of Market Concentration

The Federal Trade Commission has documented extensively how retail consolidation reshapes supplier relationships. When a single buyer controls a dominant share of any regional or national market, it acquires what economists call monopsony power — the ability to set prices not through competition but through the absence of alternatives. Farmers who want access to Walmart's or Amazon Fresh's supply chain must accept the terms those companies offer, or find other buyers who, increasingly, do not exist at the same scale.

According to USDA Economic Research Service data, the farm share of the retail food dollar — the percentage of what consumers pay that actually reaches the farm — has declined from roughly 35 cents on the dollar in the 1970s to approximately 14 cents today. The rest flows to processors, distributors, and, increasingly, to the margins of the dominant retailers who set the terms of the entire chain. This is not an abstraction. It is the mechanism by which a $4 head of romaine lettuce produces a farmworker wage that cannot cover rent in any county in California.

The Coalition of Immokalee Workers, which has spent decades organizing Florida tomato pickers, has documented how the penny-per-pound premium it negotiated with major retailers — a modest surcharge intended to pass additional income to harvesters — has been accepted by some chains and quietly circumvented by others. The margin pressure that retail giants exert on growers creates a structural incentive to treat labor costs as the primary adjustment variable, because labor, unlike land or seed, can be squeezed without appearing on a balance sheet.

The Strongest Counterargument — and Its Limits

The case for the current system rests on consumer benefit. Large retailers, the argument goes, drive down food prices for working families, and those savings are real and significant. A 2023 study from the University of Chicago estimated that Walmart's expansion into new markets reduced food prices for nearby consumers by 4 to 7 percent. For households spending a significant share of income on groceries, that is not trivial.

But this framing presents a false choice. It accepts a system in which the only mechanism for delivering affordable food to poor families is the extraction of wages from poor farmworkers — and treats that as an economic law rather than a policy outcome. Countries with strong agricultural labor protections, collective bargaining rights, and regulated retail markets manage to provide affordable food without producing a class of full-time workers who cannot afford to eat. The question is not whether consumers deserve low prices. The question is whether the cost of those prices should be borne exclusively by the people at the bottom of the supply chain.

Who Harvests What They Cannot Afford

The human profile of the American farmworker is specific and largely invisible to the people who benefit from their labor. According to the USDA's National Agricultural Workers Survey, approximately 73 percent of farmworkers were born outside the United States, the overwhelming majority in Mexico and Central America. Roughly half are undocumented, which means they have no practical access to labor protections even when those protections exist on paper. Median annual income for farmworkers hovers between $17,500 and $19,999, according to USDA data — well below the federal poverty line for a family of four.

Housing conditions in agricultural communities reflect this wage floor. In Immokalee, in California's Central Valley, in the Yakima Valley of Washington, farmworker housing is characterized by overcrowding, substandard construction, and proximity to pesticide application zones. Heat illness is endemic and underreported. The Occupational Safety and Health Administration's agricultural exemptions — which exclude farms with fewer than eleven workers from many standard protections — mean that the majority of farmworkers in the country are legally excluded from the same safety standards that govern virtually every other workplace.

The Policy Architecture That Could Change This

The tools for reform are not mysterious. The Agricultural Worker Protection Act could be strengthened to close OSHA exemptions and extend overtime protections — currently denied to most farmworkers under a Depression-era carve-out in the Fair Labor Standards Act — to the people who grow the country's food. The PRO Act, which would substantially expand collective bargaining rights, would give farmworker unions the legal standing to negotiate directly with the retailers whose purchasing decisions ultimately determine their wages.

On the market structure side, the FTC's renewed interest in monopsony enforcement — signaled under the prior administration but subject to reversal — represents an opportunity to examine whether the purchasing practices of dominant retailers constitute anticompetitive harm not just to consumers but to suppliers and their workers. Senator Cory Booker's Food and Agribusiness Merger Moratorium and Antitrust Review Act has proposed a pause on agricultural consolidation pending a comprehensive review. It has not advanced.

What the Consolidation Signals

The concentration of retail food power in the hands of two or three corporations is not merely an economic story. It is a governance story — about who in a democratic society gets to set the terms of how essential goods are produced and distributed, and who bears the cost when those terms are set by entities accountable to no one but their shareholders. The farmworkers who feed this country are not a rounding error in someone else's supply chain. They are the foundation on which the entire edifice rests.

A food system that generates record profits for its distributors while the people who harvest its products cannot afford basic necessities is not efficient — it is extractive, and the country that tolerates it has made a choice about whose labor counts and whose dignity doesn't.
