Okay, so I do less computer programming for money, but it's still a hobby and I contribute to a few open source projects.

But here are a few things that wouldn't get done if I were still employed:

• regular classes in internet security and privacy to help keep community members safe online.
• volunteering at the school to help teach students both new technologies (3D printing, robotics, environmental data collection and analysis) and old (boat building, sailing, winter survival in nature) plus tutoring in everything from music performance to math.
• serving with the emergency measures organization

That's approximately where my list ends, but fellow retirees are helping less abled people stay in their homes and communities, showing up at social justice rallies, and a myriad of other things that are important both societally and economically. If it's judged to be less important than employment, it's also important to note that much of it wouldn't be societally affordable without our free labour, yet has profound impacts on quality of life.

And I disagree that removing incentives leads to less being done. External incentives, like paycheques, are probably the least effective incentives there are. Most people are motivated by passion, desire, contribution, and satisfying results.
