With respect, I think you have it entirely backwards.
(First, "passive income" means "almost hands off, but not entirely")
Progress in technology is making things - better quality, less effort. Amazon Warehouses for example. Just a few years ago they took at least a few dozen people in rotation, now takes a man and a dog - the man to feed the dog and the dog to bite the man if he falls asleep.
Since so much can be done with so little effort it seems natural that if wealth doesn't concentrate at the top then most people would have essentially passive income streams.
