I think most people will continue to work, simply because people generally like having more money. What will stop is degrading bullshit jobs for little pay. Businesses that rely on those jobs will disappear, unless they manage to make their jobs more attractive. Businesses will have to work harder to attract employees, because employees are less desperate for work. More of the profit will go to employees, less to upper management and shareholders. I think that's a good thing.
Unless those jobs can be automated completely, of course. But then, GDP is fine, taxes will probably focus more on corporations, and people will be freed from the degrading bullshit jobs, free to look for something better. And that, I think, is also a good thing. Let the robots do the stupid work, while we're off doing more fun stuff.
Make sure technology makes everybody's lives better. Isn't that the entire point?
