I’m reading Peter Kropotkin’s The Conquest of Bread right now. (You can read it too, on Project Gutenberg!) It’s an extremely inspiring read, and very relevant still.

When Kropotkin wrote it, in the late 19th century, he quoted estimates that each person of working age would need to work four or five hours a day in order to provide for all the necessary food, goods and infrastructure. (With the technical advances we have made since then, today that would probably be even less.) After this necessary manual labour is done, people could invest the rest of their days in pursuing their own personal interests in sciences, arts, publishing, playing with doggies, etc.
