As a college instructor, at some point in my classes I ask my students “Do you think you and the other workers could run your workplace without your boss?” Surprisingly, more than half say they can. But where their eyes glaze over is when I ask them “Do you think you could coordinate your efforts with workers in other areas into some kind of confederation?”
Michael Albert has written a book that spells out in detail how things could be coordinated. He deals with such topics as “should people be entitled to parental inheritance”; “is it possible to coordinate exchange of products without money”; “is it possible to use money without it becoming capitalism” as well as “how workplaces could be run without bosses”. The linked article is just a taste of what is in his book.
