Add to this, what i believe will happen, is what, in Japan are called Halfus (Half oos)
Half farmer, half something else.
Everyone will grow their own food. And with modern agriculture advancements, this can be done in 10 hours a week.
Then with community sized, continuous, green power generation, the meaning of a job, trading time for money becomes useless.
You have your needs met, what you want are things you can't produce, and so a trade economy develops, where it is not about profit margins.
Of course, capitalism will be in full effect (its original meaning), but the capital in question is machinery, raw materials and labor available.
The abomination that is capitalism today: A young chemical engineer figured out how to crack oil for ¼ the energy, but it was never implemented... because it would lower the profit margin. If you make it 4x as cheap, you have to sell 4x more to make the same profit.
