It's global, and we're already seeing trouble. It takes a relatively small percentage of people to do the real work. The problem is what to do to occupy people with no responsibilities and lots of idle time. The drug epidemic, unruly behavior, violence/terrorism and a lack of achievement are all at least in part due to young people being enabled to lead unproductive lives with no responsibilities to others.
These scenarios never end well in movies about the future.
