Is capitalism a good thing? Journalist Katherine Mangu-Ward makes the case that "weirdos" left alone to innovate and explore far-out ideas in a free market system are our best hope for the future. She asks us to reconsider our qualms about capitalism, failure and corporate death, analyzing the recent history of General Motors and Facebook to illustrate why we're better off with a lot less government intervention.

As the saying goes, less is more. The same goes for words. Listen as Politico and Axios co-founder Jim VandeHei shares what he's learned leading two media companies -- and how to radically rethink the way you write to keep people's attention in a distracted digital world.

Social entrepreneur Bernhard Kowatsch shares real-life examples of how a business approach focused on accelerating tech (like a blockchain-supported way to bring food to refugees or a machine that fortifies flour at small mills in Africa) can help make an impact on big, seemingly intractable problems. "Innovation and technology can create so much good in the world, and together we can solve the world's biggest challenges," he says.

Even with public trust at an all-time low, Wikipedia continues to maintain people's confidence. How do they do it? Former CEO of Wikimedia Foundation Katherine Maher delves into the transparent, adaptable and community-building ways the online encyclopedia brings free and reliable information to the public -- while also accounting for bias and difference of opinion. "The seeds of our disagreement can actually become the roots of our common purpose," she says.

The weekend. Social Security. Health insurance. What do these things have in common? They all exist thanks to the advocacy of labor unions.

The traditional approach to work needs a redesign, says economist Juliet Schor. She's leading four-day work week trials in countries like the US and Ireland, and the results so far have been overwhelmingly positive: from increased employer and customer satisfaction to revenue growth and lower turnover. Making the case for a four-day, 32-hour work week (with five days of pay), Schor explains how this model for the future of work could address major challenges like burnout and the climate crisis -- and shares how companies and governments could work together to make it a reality.

When women lead, bias often follows. Documentarian Robin Hauser dives into the dilemma between competence and likability faced by women in leadership roles, detangling the unconscious beliefs and gendered thinking that distort what it means to be a good leader.

What's a company's purpose? It's not the same as mission or vision, which change when leadership changes. Strategist Ashley M. Grice explains the power of purpose to push boundaries of innovation and bring clarity to every aspect of an organization, from the top floor to the shop floor.
