On page 239 of What Happened, Hillary Clinton reveals that she almost ran a very different campaign in 2016. Before announcing for president, she read Peter Barnes’s book With Liberty and Dividends for All, and became fascinated by the idea of using revenue from shared natural resources, like fossil fuel extraction and public airwaves, alongside revenue from taxing public harms, like carbon emissions and risky financial practices, to give every American “a modest basic income.”

Her ambitions for this idea were expansive, touching on not just the country’s economic ills but its political and spiritual ones. “Besides cash in people’s pockets,” she writes, “it would be also be a way of making every American feel more connected to our country and to each other.”

This is the kind of transformative vision that Clinton was often criticized for not having. It’s an idea bigger than a wall, perhaps bigger even than single-payer health care or free college. But she couldn’t make the numbers work. Every version of the plan she tried either raised taxes too high or slashed essential programs. So she scrapped it. “That was the responsible decision,” she writes. But after the 2016 election, Clinton is no longer sure that “responsible” is the right litmus test for campaign rhetoric. “I wonder now whether we should’ve thrown caution to the wind, embraced [it] as a long-term goal and figured out the details later,” she writes.
