The times demand serious economic ideas. Harris supplies gimmicks.

Vice President Kamala Harris’s speech Friday was an opportunity to get specific with voters about how a Harris presidency would manage an economy that many feel is not working well for them. Unfortunately, instead of delivering a substantial plan, she squandered the moment on populist gimmicks.

Americans are clearly still anxious and angry about the high cost of groceries, housing and even $5.29 Big Macs. While the inflation rate has cooled substantially since the 2022 peak, an ostensible Biden-Harris administration accomplishment, prices remain elevated relative to the Trump years. So it’s a real political issue for Ms. Harris. One way to handle it might be to level with voters, telling them that inflation spiked in 2021 mainly because the pandemic snarled supply chains, and that the Federal Reserve’s policies, which the Biden-Harris administration supported, are working to slow it. The vice president instead opted for a less forthright route: Blaming big business. She vowed to go after “price gouging” by grocery stores, landlords, pharmaceutical companies and other supposed corporate perpetrators by having the Federal Trade Commission enforce a vaguely defined “federal ban on price gouging.”
