The Robinson-Patman Act is a dated idea being pushed back into play, and this piece argues why reviving it would hurt consumers, punish efficiency, and hand regulators too much power. It walks through the law’s origin, modern market realities, the economic case against reviving it, and the political drive behind the push.
Some bad ideas refuse to die, and the Robinson-Patman Act is one of those fossils. Born in the 1930s, it banned wholesalers from giving lower prices to big retailers than to small ones, treating volume discounts as if they were villainous rather than ordinary business practice. Back then politicians painted large chains as bullies squeezing out mom-and-pop shops, but they ignored the basic fact that lower wholesale prices usually meant lower retail prices for shoppers.
When Congress decided efficiency looked like exploitation, the result was higher prices and fewer gains for consumers, not a miraculous return of failing small stores. Over time courts and agencies scaled the law back because market reality reasserted itself: competition and scale often benefit buyers. The lesson is simple, if inconvenient for price-checking populists.

Now, nearly a century later, some on the left want to dust off the RPA concept and treat volume-based pricing differences as evidence of unfairness. Their argument calls price discrimination a market sin that requires government oversight to fix Main Street. That framing flips the burden of proof and assumes markets that produce lower prices for consumers are automatically suspect.
Brent Skorup’s piece “Stop Making Sense: Reviving the Robinson Patman Act and the Economics of Intermediate Price Discrimination” tears through that logic. He shows that differences in the prices offered to large and small buyers are not proof of harm but the mechanism that keeps competition alive and prices low. In a free economy, sellers tailor prices to different buyers because costs and efficiencies differ, and that flexibility benefits the public.
Today’s economy depends on customization and dynamic pricing in ways the 1930s never imagined. Airlines, e-commerce platforms, and modern logistics use variable pricing and volume discounts to match supply with demand and reward efficiency. Treating intermediate price discrimination as a regulatory problem would force the market into crude uniformity while rewarding inefficiency.
When firms like Walmart or Costco use scale and logistics to lower costs, consumers see the payoff at checkout. Volume discounts reflect lower per-unit costs and broader distribution, not some secret scheme to crush competition. Penalizing these practices would be like telling airlines they must charge everyone the same for a seat regardless of booking date and demand. It would be economically backward.
SOCIALIST MAMDANI’S SUPERMARKET PLAN WOULD BE ‘BULLET TO THE HEART’ OF BLUE-COLLAR AMERICA, LAWMAKER WARNS
The push to revive Robinson-Patman fits a trend: using antitrust law as a tool for social engineering rather than protecting consumers. Figures who favor aggressive regulatory activism see antitrust as a way to reshape market outcomes to their political tastes. That mindset threatens to replace market signals with regulatory bargaining and litigation incentives.
For decades mainstream antitrust focused on consumer welfare: lower prices and more output mean markets are working. Swapping that test for a regime obsessed with protecting competitors would favor special interests and litigious actors over shoppers. Bureaucrats and trial lawyers would gain the power to police pricing decisions, chilling investment and innovation.
Skorup warns that giving regulators discretion to decide which pricing differences are “reasonable” would make pricing a political act. Companies would calibrate behavior to avoid scrutiny rather than to serve customers, and investment in better logistics and distribution would slow. That is a loss for consumers and a step toward regulatory favoritism posed as fairness.
State-level copycats and opportunistic lawsuits already threaten to spread these theories even without a federal resurrection of the RPA. The net effect would be regulatory uncertainty, fewer experiments in supply chains, and ultimately higher costs for households who rely on discount retailers for everyday essentials. That is the opposite of pro-consumer policy.
Policymakers who care about living standards should reject calls to resurrect a Depression-era rule that punished the very efficiencies that improved American living standards. Competition, choice, and voluntary exchange built our economy. Returning to command-and-control pricing would not help Main Street; it would force everyone to pay for the policies of a misguided past.
