Reasonably Optimistic

Zohran Mamdani ran for mayor of New York on a platform of taxing the rich, proposing new levies targeting billionaires. Host Megan McArdle argues we’ve seen this kind of rapid shift before.

In the 1970s, New York spiraled into crisis as rising spending, a shrinking tax base and economic change led to crime, population loss and near-bankruptcy. Those lessons still matter today, especially as remote work and mobile wealth make cities more vulnerable to decline. But these same forces also create opportunities for cities that adapt, grow and make themselves attractive places to live and work.

Social media is designed to keep us scrolling. But is it also keeping us angry? Rage bait is rewarded and amplified. It’s easy to react and even easier to get pulled in. Over time, this has changed how we interact with the world — and with each other. But is this just bad behavior, or something closer to addiction?

Host Megan McArdle is joined by Keith Humphreys, a Stanford professor and psychologist, to break down the mechanics of addiction and how they might apply to life online. Together, they explore why rage is so compelling, how platforms keep us hooked and whether it’s possible to break the cycle.

Is this just a temporary trend, or something deeper — and what does it mean for the kind of society we’re building?

Host Megan McArdle is joined by economist and demographer Lyman Stone to discuss what’s really driving the decline in birth rates — from delayed marriage to cultural shifts and rising anxiety about the future.

From overdone plastic surgery to open-concept floor plans, we’re designing our lives to look good on camera instead of optimizing for what we need. Influencer culture — and our constant exposure to curated, edited and optimized images — has reshaped the way we see the world and ourselves. But chasing the perfect image can leave real life feeling strangely hollow.

Host Megan McArdle unpacks how we got here — and how to start seeing past the screen.
