The (Other) Southern Strategy: Domestic Labor Arbitrage and the Road to Globalization

The conventional account of American deindustrialization begins with globalization: trade barriers were lowered, capital flowed, and firms pursued the lowest costs abroad. That story is correct, but incomplete. Long before trade liberalization facilitated offshoring, the United States fractured its labor system at home. The result was a domestic version of labor arbitrage that prefigured, and ultimately enabled, the waves of offshoring that followed. As America returns its attention to the importance of industrial strength, it is useful to understand our own economic history, and what it teaches about the long-run cost of rooting industrial competitiveness in labor’s weakness.

This earlier, pre-globalization shift—from North to South, from higher wages to lower ones, from high union density to right-to-work jurisdictions—reshaped the terms of industrial competition in the United States. It revealed how governments could achieve economic growth through institutional retreat from organized labor rather than investment in productivity. It also demonstrated that the reallocation of industrial capacity, far from being a purely market-driven process, could be the consequence of deliberate policy choices about the distribution of power within an economy.

Understanding this history matters not only for what it explains about the past, but for what it implies about the conditions under which productive capacity and rising wages can coexist as the United States works to rebuild its atrophied industrial base. Before capital sought leverage abroad, it learned how to exercise it at home. To understand how that leverage developed, we must examine the industrial migration that reshaped America’s economic geography in the mid-twentieth century.

Crossing State Lines: A Domestic Development Strategy

The broad contours of this internal shift are well known. After 1947, as states across the South enacted right-to-work (RTW) laws authorized by the Labor Management Relations Act, commonly known as the Taft–Hartley Act, manufacturers quickly realized that they could lower labor costs and dilute the bargaining power of unions simply by crossing state lines. Economist Thomas Holmes has captured this phenomenon with a simple border test, finding that when moving from a non-RTW to an RTW state, manufacturing activity increases sharply.

The firm-level rationale is straightforward. RTW weakened unions’ ability to collect dues by prohibiting closed shop and agency fee arrangements, and undermined contract coverage, eroding the strength of a countervailing power that put upward pressure on compensation. The academic literature consistently finds that a state’s adoption of RTW results in immediate, dramatic declines in organizing activity and, in the longer term, a reduction of about 5-10% in union membership. For managers seeking to boost profits, the value proposition was clear: relocating across state lines often reduced labor costs without sacrificing access to the national market.

This “Southern strategy” was not merely about RTW laws. As historian James C. Cobb notes, it was part of the region’s “crusade for industrial development,” a decades-long political campaign by Southern politicians and developers to “sell” the South as a low-cost, business-friendly alternative to the unionized North. The pitch went beyond cheap labor: it bundled RTW governance with favorable tax treatment, publicly funded industrial parks, infrastructure subsidies, and a more permissive regulatory climate.

Together, these tools advanced a developmental narrative that appealed to localities hungry for jobs and firms seeking relief from rising costs and adversarial labor relations. The very success of the campaign, however, normalized a policy mechanism in which wage restraint and the dilution of worker power became legitimate instruments of industrial strategy. Management’s credible threat to relocate to the South became a structural constraint on labor’s bargaining position, chilling wage demands, and undermining union density even in non-RTW states where labor protections formally remained intact.

This internal industrial migration brought real and overdue gains to the South: job creation, capital investment, and the establishment of advanced manufacturing ecosystems in previously under-industrialized regions. For communities long shut out of the American economic growth engine, these were transformational improvements. Firm-level studies find that RTW adoption is associated with increased business investment, higher employment, and greater profits—a result that aligns with lower labor costs and a diminished union presence. For firms facing import competition beginning even in the 1960s and 1970s, a lower domestic cost base arguably enabled production to continue that might have otherwise been rendered uneconomic. Moreover, if regions differ in factor prices, it is unsurprising that capital would flow toward lower-cost jurisdictions. In textbook terms, this reallocation is efficient: companies can achieve the same output with less expense, which theoretically results in lower consumer prices.

But the national ledger reads differently. First, the “efficiency” claim assumes lower wages reflect productivity-enhancing reallocation rather than a transfer from labor to capital. But studies of firms operating in RTW states find that while wages tend to fall, firms often redirect financial gains toward returning cash to shareholders via stock buybacks and dividends—a pattern consistent with increased bargaining power for ownership. Location studies confirm that manufacturing activity reallocates toward RTW jurisdictions; however, there is little compelling evidence that those shifts deliver a productivity premium. Although comprehensive state-level data on manufacturing productivity during this period are limited, firm-level research frequently finds that the effects on total factor productivity are mixed at best and sometimes negative. When the basis of competition is lower labor costs rather than higher labor productivity, the resulting “efficiency” accrues less to the economy as a whole—or to the long-term health of the industrial base, as we will see—and more to shareholders and executives, indicating a redistribution from labor to capital rather than a genuine gain in productive output.

Second, and most important for the argument of this essay, the Southern strategy institutionalized a logic of competition that would later scale globally. This logic reflects an economic mechanism referred to as Michal Kalecki’s Paradox of Costs. Put simply: higher wages, in the aggregate, are not a drag on growth; they fuel demand, reward investment in productivity-enhancing capital expenditures, and set off a virtuous cycle in which rising productivity and rising wages reinforce one another. At the firm level, the temptation is the opposite: hold wages down to outcompete their competitors on costs. But what helps one firm’s balance sheet can weaken the very consumer market all firms depend on if applied across the economy. In a system where investment is constrained by consumer demand, widespread wage suppression forces a stark choice: either household and public debt increase to compensate for lost purchasing power, or output, and eventually profits, slow. The Southern strategy normalized this firm-level incentive, making mobility and wage restraint an easy way to boost profit relative to the harder, more challenging work of increasing productivity.

Free Riding on Demand, at Home and Abroad

In the international trading system, as Michael Pettis has noted, nations like China that free-ride on their trading partner’s demand while suppressing the incomes of their workers undermine a collective imperative of higher wages that would generate greater demand and spur investment globally. This strategy has inherent limits that, as Mark DiPlacido explains, China is now confronting. But the same logic applies to intra-national labor arbitrage. The United States’ “internal free-rider problem” was engineered through law (Taft-Hartley), fiscal policy, and a less onerous regulatory environment. Once firms and subnational governments learned to compete by undercutting each other’s wage floors and labor and employment standards, extending the strategy from the Mason-Dixon Line to the Rio Grande required only a modest conceptual leap.

Labor scholar Kate Bronfenbrenner, in a study prepared for the U.S. Trade Deficit Review Commission in 2000, found that more than half of employers faced with union organizing campaigns during the 1990s threatened to close their plants if workers voted to unionize. In highly mobile industries like manufacturing, that number approached 70%. Her research documented how such threats became a normalized feature of management’s playbook, chilling organizing efforts and demonstrating how capital mobility evolved into a tool of labor discipline.

Interpreted through this lens, the domestic migration of industry did not merely precede globalization. Rather, it softened the political and managerial constraints that might otherwise have resisted offshoring. A firm that had already learned to bargain with its workforce by threatening to relocate to the South was well-positioned to threaten relocation abroad. The geographical migration of electronics company RCA Corporation from Camden to Bloomington to Memphis to Juárez—chronicled in Capital Moves: RCA’s Seventy-year Quest for Cheap Labor—is not an idiosyncratic corporate saga, but a template for industrial mobility under wage-suppression regimes. Indeed, the trajectory of the once-great American company is a microcosm of a broader industrial logic that scaled from state to state, then across national borders. Domestic arbitrage was the opening act. International arbitrage stole the show.

Where, then, does the Southern strategy fit in a broader political economy of American deindustrialization? Its deeper legacy lies in establishing a model of cost-based competition that discouraged productivity-enhancing investment and proved easily exportable. Once the terms of comparative advantage are structured on the dimension of wage suppression, domestically or internationally, investment will chase the highest after-wage return, and employers will invest more in bargaining for cheaper labor than in reorganizing production to raise the productivity of more expensive labor.

Kalecki’s Paradox of Costs clarifies the dynamic. If higher wages across a system raise household income and incentivize firms to invest in labor-saving technologies, they promote a virtuous circle of productivity growth. However, any firm—or state or nation—that breaks ranks by cutting wages below the prevailing norm can underprice competitors in tradable goods while free-riding on demand generated elsewhere. In an open federal system with a bifurcated labor system, it flourished as a development strategy. In an open international system with no practical constraint on labor-suppression subsidies, it became a structural driver of imbalances.

These dynamics raise a broader question: can a common market function without common rules? A fragmented system of labor regulation, in which firms suppress wages in one jurisdiction while selling into high-wage markets, builds in the very imbalances that Taft-Hartley enabled and globalization later amplified. What is needed is not to reverse Taft-Hartley and return to uniformity for its own sake, but a new framework that supports sectoral bargaining, worker voice, coordination across jurisdictions, and aligns with a broader principle that competition should be predicated on innovation and capability rather than the suppression of worker power. That principle must also guide international competition: neither trading partners nor multinationals should be rewarded for racing to the bottom on labor standards.

Not all policy divergence in a common market creates the same distortions. Tax policy, for instance, may vary without necessarily eroding the foundations of a common market. Unlike labor arbitrage—where firms can pay lower wages in one jurisdiction and still rely on the demand generated by high wages elsewhere—tax policy, and the public services it finances, are largely linked geographically. A state offering lower taxes may also provide fewer services, ensuring businesses bear both the costs and the benefits.

Labor, however, is different. Because firms can simultaneously realize the benefits of demand elsewhere and the benefits of lower wages paid to their own workers, cost-based competition over labor standards is far more prone to imbalance. Once mobility became organized around labor-cost arbitrage, it ratified the free-rider logic that Kalecki warned against and advanced the same kind of “labor repression as industrial subsidy” dynamic that Pettis and DiPlacido have written about in the context of our broken international trading system. In the short term, firms invested more and profits rose as labor’s share of income fell; in the medium term, union density eroded and the discipline of leveraging a credible exit replaced the discipline of enhancing productivity; in the long term, the industrial base fragmented into a market of competitors competing on cost rather than capability.

Globalization Began at Home

The implication is that domestic and international arbitrage should be treated as a single phenomenon, rather than as separate epochs. The same logic—minimize labor’s bargaining power to create a local cost advantage, and rely on other jurisdictions to supply the consumer demand—operates across state lines and national borders. The scale differs, but the mechanism is the same. If we want to understand why American firms became so nimble at escaping labor and employment standards and why policymakers became so comfortable underwriting that escape, we must start with Taft-Hartley, and with the plant-closing threats that made relocation a common bargaining tactic. The story of globalization, in other words, began at home.

The U.S. industrial system has never been neutral toward the architecture of its labor market. The domestic migration of manufacturing capital in the postwar decades was more than efficient reallocation of productive resources. It was a formative chapter in the remaking of industrial norms, of what counted as acceptable competitive practice, and of how firms balanced the imperatives of innovation, investment, and labor discipline. The South’s industrial growth was both overdue and beneficial to the United States, and some of its methods merit replication. But insofar as the mode through which it was achieved was anchored in wage suppression and union dilution, it set a pattern that proved hard to break.

That underlying logic has endured. The idea that investment follows the path of least resistance, wherever labor costs are lowest and worker power and voice are weakest, was pioneered on American soil before it extended to new frontiers beyond our borders. As U.S. policymakers once again pursue reindustrialization, the question is not only how to rebuild industrial capacity, but under what conditions. The twentieth century demonstrated that productive dynamism and strong labor institutions are not mutually exclusive; indeed, they coexist and drive one another when the benefits of growth are shared. If the goal is to rebuild an industrial base that is not merely bigger in the short-term but better in the long-term—more productive, more prosperous, and more willing to share prosperity with the workers who create it—then we must confront how the pursuit of growth at labor’s expense undermined America’s industrial strength from within. The success of any reindustrialization agenda will depend on learning the lesson.
