Capitalism has a PR problem. Martin Whittaker thinks the solution isn't abandoning it but rather making it work better for more people.

Martin is the CEO of JUST Capital, an organization built around a big idea: Business can be one of our most powerful tools for solving society's toughest problems, particularly when doing good and doing well point in the same direction.

In this week's episode of Power & Impact, we talk about why Martin chose business after earning his Ph.D., how JUST Capital set out to "bend the arc of capitalism," and why jobs, wages, opportunity, and economic security matter so much to people's faith in the system.

We also explore AI. Martin sees enormous potential for the technology to boost productivity and expand opportunity. How businesses put it to work will help determine what that opportunity looks like, especially for young people trying to find the entry-level jobs that have traditionally launched careers.

Finally, we discuss philanthropy, incentives, the power of work, and creative approaches that bring business and social purpose together to solve difficult problems.

It all comes back to one question: How do we build a future in which more people believe they have a stake?

What does it really take to build something that lasts? Starting something is hard. Making it successful is even harder. But building something that can survive changing markets, new technology, different generations and challenges you never saw coming takes something more.

In this final episode of our Lessons Learned series, I look back at conversations with leaders who have built organizations and brands designed to endure.

Jeff Sprecher shares how he recognized the lasting value of the New York Stock Exchange and why sometimes building the future means knowing what is worth preserving.

Alan Fuerstman explains why culture, people and knowing what your brand stands for matter more than simply chasing growth. Omer Acar shows how powerful culture can become when employees are trusted and empowered to create meaningful experiences for customers.

And Judy Marks shares why a company with nearly 173 years of history still has to embrace AI, technology and change to remain relevant. The lesson I took away from all of them is simple. Building what lasts doesn't mean building something that never changes.

It means creating a strong enough foundation to evolve without losing what made it special in the first place. That's what I've learned about building what lasts.

What if living longer isn't actually the goal? What if the real goal is living better?

In the third episode of Lleadership lessons, we explore the longevity playbook with some of the leading voices in health, wellness, and purposeful aging. From the Blue Zones and the foods that help people live longer, to chronic disease, lifestyle medicine, sleep, stress, relationships, biological age, and the power of community, this conversation looks at what really matters when it comes to adding more healthy years to our lives.

We talk about why our closest relationships can influence our health, why fear isn't always enough to change our behavior, how lifestyle choices can make a difference, and why our genes may not determine our destiny.

But longevity isn't just about adding years.

It's about purpose. It's about staying connected. It's about continuing to learn. And as one guest puts it, maybe the goal isn't to stay youthful forever — maybe it's to stay useful.

This is The Longevity Playbook.

What can you change today to make the years ahead healthier, more meaningful, and more connected?
