I'm not confident that Unions would work for huge issue that is coming up - Mass Mechanization. There will be very few jobs Robotics will not be able to replace in a decade or so. This will easily facilitate few people owning large chunks of means of production. I don't see any serious solutions to this issue on the horizon.
