In the original Alien movie, the crew of the USCSS Nostromo works as interplanetary haulers for the Weyland-Yutani Corporation. They wake from cryosleep and discover an eerie signal on a distant moon. Despite safety concerns and a desire for overtime pay, they’re forced by contract fine print—enforced by a company-programmed android—to investigate. That decision leads to a face-hugger attack, a chest-bursting alien specimen, and multiple crew deaths. Behind the scenes, company orders label the crew “expendable,” revealing a ruthless bid to capture the alien for weapons research. Economists call this one-buyer-dominated scenario a monopsony, the flip side of monopoly. When a single employer controls most local hiring, workers can’t easily quit or demand better wages. Historically, textbooks pointed to remote mining towns as classic examples. In The Wage Standard, Arindrajit Dube argues monopsony power is far more widespread today—even in urban markets with many firms—because factors like geographic immobility, limited wage transparency and noncompete clauses weaken worker leverage. Dube traces rising income inequality since the 1980s to the erosion of counterweights: declining union membership, stagnant minimum wages and lax antitrust enforcement. Without unions or strong labor laws, companies quietly suppress wages and benefits. Yet he spots signs of revival—recent minimum-wage hikes, renewed antitrust scrutiny and worker organizing—that could rebalance power. Next week’s Planet Money newsletter will explore his evidence on monopsony’s reach and his proposals for reform.
