Lina Khan, the youngest F.T.C. chair in history, reset U.S. antitrust policy by thwarting mega-mergers and other monopolistic behavior. This earned her enemies in some places, and big fans in others — including the Trump administration. Stephen Dubner speaks with Khan about her tactics, her track record, and her future.

But now it may be keeping us from pursuing strategies that would improve the environment, the economy, even our own health. So is it time to dial down our disgust reflex? You can help fix things — as Stephen Dubner does in this 2021 episode — by chowing down on some delicious insects.
